There’s a certain pride that comes with keeping an older truck on the road. My 2004 GMC Sierra has been a steadfast companion, a workhorse that has never let me down. But years of sun, road debris, and countless car washes had taken their toll on its face. The original headlights, once crystal clear, were now a cataract-clouded, yellowed mess. Night driving had become an exercise in squinting, the weak, diffused beams doing little to inspire confidence on dark backroads. The truck ran like a top, but it *looked* tired. Restoring the old lenses felt like a temporary fix, so I began the hunt for a full replacement—a way to give my faithful Sierra a much-needed facelift and restore its night-vision, all without breaking the bank. This search for an affordable, OEM-style solution led me directly to the complete four-piece kit from DNA Motoring.
What to Consider Before Buying Aftermarket Headlight Assemblies
An automotive headlight assembly is more than just a bulb and a lens; it’s a critical safety component and a defining aesthetic feature of your vehicle. It’s the solution for compromised night visibility caused by hazing, yellowing, or internal damage to the original units. A new set can dramatically improve light output, creating a safer driving experience, while simultaneously refreshing the vehicle’s appearance, effectively making an older car or truck look years younger. For owners of vehicles like the venerable 1999-2007 Sierra and Yukon, where original parts can be expensive or hard to find, a complete aftermarket kit presents a compelling value proposition.
The ideal customer for this type of product is a hands-on vehicle owner facing diminished light performance or cracked housings on a daily driver, or someone restoring a project truck on a budget. They understand that a complete replacement is often more effective and sometimes easier than a multi-step restoration process. However, these kits might not be suitable for those seeking a high-performance, custom lighting solution with features like advanced projectors or unique LED signatures. Owners of pristine, show-quality vehicles might also prefer to source genuine OEM parts to maintain originality, despite the higher cost. For those seeking a different style, options range from smoked lenses to assemblies with integrated LED accents.
Before investing, consider these crucial points in detail:
- Vehicle Fitment & Compatibility: This is the most critical factor. Double-check that the assembly is designed for your exact year, make, and model. Pay close attention to trim levels. As one user discovered, a set designed for a standard Yukon will not fit a Denali trim due to differences in the grille and front fascia. Always verify compatibility with your specific vehicle, noting any exceptions like “Classic” body styles for certain model years.
- Light Performance & Bulb Type: Understand what you’re getting. This particular kit requires 9005 high beam and 9006 low beam bulbs, which are not included. This allows you to choose between standard halogen, brighter halogen, or compatible LED or HID upgrades. However, the ultimate performance is dictated by the reflector and lens quality. A poorly designed reflector can result in a scattered, ineffective beam pattern, regardless of how powerful the bulb is.
- Materials & Durability: The housing is typically made from ABS plastic, while the lens is polycarbonate. While polycarbonate offers excellent impact resistance and clarity, its long-term durability depends on the quality of the UV-protective coating. Cheaper coatings can lead to premature yellowing or hazing, putting you right back where you started. Similarly, the quality of the housing plastic affects the mounting tabs’ strength and the overall robustness of the unit.
- Sealing & Weather Resistance: A headlight’s worst enemy is moisture. A poor seal between the lens and the housing will allow condensation to form, fogging the lens from the inside and potentially shorting out electrical components. Look for units with high-quality butyl rubber sealant. Some users of budget-friendly kits recommend adding an extra bead of silicone around the seam as a preventative measure.
While the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights offer a complete solution for many GM trucks, understanding the broader landscape of lighting technology is beneficial. For a deeper dive into what makes a great headlight, especially in the off-road space, we highly recommend reading our comprehensive guide.
First Impressions: A Promising Facelift in a Box
The DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights arrived in a large, unassuming cardboard box. Inside, the four pieces—two main headlight assemblies and two lower bumper/turn signal lights—were neatly separated and wrapped in protective film. Pulling them out, the initial visual impact was impressive. The chrome housing was bright and reflective, and the amber side markers and reflectors were clean and vibrant. Compared to the dull, sandblasted originals I had just pulled off my Sierra, these looked like jewels. They felt incredibly lightweight, which gave me my first moment of pause. The plastic of the rear housing felt thinner and more flexible than the thick, rigid material of the OEM units. Tapping on the polycarbonate lens produced a sharp, hollow sound. While they looked the part of a factory replacement, the tactile feedback hinted at their budget-friendly price point. Still, for the cost of a single OEM unit, I had a full four-piece set that promised to completely transform the front end of my truck. The potential for a dramatic aesthetic upgrade was undeniable, and a quick look at the price confirms it’s one of the most affordable options available.
What We Like
- Complete four-piece set offers a comprehensive front-end refresh
- Excellent initial appearance with bright chrome and clear lenses
- Direct OEM styling provides a clean, factory look
- Extremely affordable price point for a full set of lights
What We Didn’t Like
- Build materials feel thin and fragile, especially mounting tabs
- Prone to quality control issues like poor seals and broken parts on arrival
Performance Under Pressure: A Deep Dive into the DNA Motoring Headlights
A new set of headlights has to do more than just look good; it has to fit correctly, illuminate the road effectively, and withstand the elements. We put the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights to the test, evaluating every aspect from the moment we opened the box to weeks of real-world night driving. Our experience was a mix of pleasant surprises and significant frustrations, painting a clear picture of a product where price is the primary driver, and performance comes with major caveats.
Installation and Fitment: A Tale of Two Experiences
On paper, swapping headlights on a GMT800 platform truck like a Sierra or Yukon is one of the easiest jobs an owner can do. It involves pulling two pins, sliding the old assembly out, disconnecting the bulbs, and reversing the process. Many users reported completing the job in as little as 15 minutes. And indeed, removing the old, factory lights was a breeze.
However, installing the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights proved to be less straightforward. We immediately noticed that the plastic mounting brackets and guide pins didn’t have the same precise tolerances as the OEM units. Getting the main headlight assemblies to slide into place required a significant amount of wiggling and careful pressure. This is where the fragility of the plastic becomes a major concern. As one user noted, “don’t force it..that how a lot of them break is during install.” We can confirm this sentiment; the fear of snapping a crucial mounting tab with one misplaced push was ever-present. The retaining pins were much harder to re-insert, suggesting the holes weren’t perfectly aligned.
The lower bumper lights presented their own challenge. A common complaint we validated was the weakness of the retaining clip. The OEM clip snaps into place with a satisfying, secure click. The DNA Motoring clip, by contrast, felt mushy and didn’t provide enough tension to hold the housing firmly. We experienced the light assembly feeling loose and even popping out of place with a slight nudge. This echoes the feedback from a user who cleverly “wedged a piece of 1/8” rubber tubing inside clip and it secured snuggly.” While this is a creative fix, it’s a modification that shouldn’t be necessary. Ultimately, we achieved a secure fit, but it required more patience, careful alignment, and troubleshooting than a simple “plug-and-play” installation should. The fitment is iffy at best, and the process can be frustrating for those expecting a seamless OEM-like experience.
Build Quality and Durability: You Get What You Pay For
This is, without a doubt, the product’s greatest weakness. From the moment you handle them, the cost-cutting measures are apparent. The housing plastic is noticeably thinner and more brittle than the factory units. We saw numerous reports of users receiving units that were broken in the box, specifically at the mounting points. One customer stated, “Picked up a headlight and immediately noticed the plastic attachment bracket molded to the headlight was broken. Junk.” While our set arrived intact, we can easily see how a minor drop or shipping impact could cause catastrophic damage.
The most critical aspect of durability for a headlight is its seal against moisture. After several rainy days and a few trips through a drive-through car wash, we were disappointed to see a fine layer of condensation forming inside the passenger-side headlight. This confirms reports from other users about improper sealing. Once moisture gets inside, it’s nearly impossible to remove, leading to a perpetually foggy appearance and drastically reduced light output. It also creates a high risk of corrosion on the bulb connectors and reflective surfaces over time.
Furthermore, we read several accounts of the polycarbonate lenses yellowing and hazing after just a few months of use. This suggests the UV-protective coating is either very thin or of poor quality. While they look fantastic right out of the box, their long-term aesthetic appeal is highly questionable. The entire assembly feels loose and shaky even when installed, leading to a “bouncy” beam on the road, a problem noted by multiple users. This is a direct result of the flimsy plastic and poor fitment. It’s clear that while the low price is tempting, it comes at the direct expense of material quality and long-term resilience.
Light Output and Beam Pattern: A Step Sideways, Not Forward
The ultimate purpose of a headlight is to illuminate the road. My original, hazy OEM headlights were failing at this job, casting a dim, scattered light. I had hoped that the new, crystal-clear lenses and clean reflector bowls of the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights would be a night-and-day difference. Unfortunately, the results were deeply underwhelming.
We installed a new set of standard Sylvania halogen bulbs (9006 low beam, 9005 high beam) for our test. The light produced was certainly “cleaner” than the yellowed haze of the old units, but the beam pattern itself was poor. There was no distinct, sharp cutoff for the low beams, leading to a diffused wash of light with several noticeable hotspots and dark patches. The effective throw distance down the road was not a significant improvement over the clouded originals.
The situation worsened with the high beams. As one user perfectly summarized, “High beam is just a bit brighter than low should be. Nobody flashes high beams if I have my high beams on.” We found this to be precisely the case. The high beam setting adds some height to the beam but does little to increase the intensity or distance, failing to provide the confidence needed for driving on unlit highways. We attempted to adjust the beam alignment using the provided screws, but they felt flimsy and offered little-to-no actual change in the beam’s direction. Several users called them “non-adjustable,” and we’re inclined to agree. The internal adjustment mechanism feels disconnected and ineffective. This is a significant safety concern, as proper headlight alignment is crucial. For those prioritizing actual lighting performance, this set is a profound disappointment. The aesthetic upgrade is the only real benefit here, not improved visibility.
What Other Users Are Saying
Sifting through feedback from other owners of the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights reveals a consistent and sharply divided consensus that hinges on expectations. On the positive side, many users are thrilled with the immediate visual impact. One owner, happy with the transformation, said, “After years of exposure to UV rays and road grime, my car’s headlights had become cloudy and dim… Rather than a restoration process, I chose to just replace them. I’m so glad I did.” Another noted, “These headlight assembly look good on my 06 Sierra… No water inside them. I use drive through car washes. I love the look.” These comments highlight the product’s primary appeal: it’s a fast, cheap way to make an old truck look great.
However, the negative feedback is substantial and focuses on the product’s functional shortcomings. The most frequent complaint is the abysmal build quality. “The headlight looks really good, but don’t buy it!!! It is cheaply, cheaply made. The plastic is light and extremely fragile,” one user warned. Another confirmed our findings about moisture, stating, “Well LA just got a bunch of rain and these headlights aren’t sealed properly wouldn’t recommend using these.” The poor light output and non-functional adjusters were also common themes, crystallizing the idea that this is a cosmetic part first and a safety component a distant second.
Alternative Headlight Assemblies to Consider
While the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights cater to a specific budget and vehicle set, it’s important to know what else is out there, especially if you drive a different truck or prioritize different features.
1. DNA MOTORING Black Housing Headlights for Ram 1500-5500
For owners of 2010-2018 Ram trucks, this alternative from DNA Motoring offers a different aesthetic. Instead of the classic chrome, it features a more aggressive black housing that provides a “smoked” or custom look without dimming the light output. Like the Sierra model, it’s designed as a direct OEM replacement but for the dual or quad headlight Ram models. This is a great choice for Ram owners who want to de-chrome their front end and achieve a more modern, aftermarket style. Build quality concerns would likely be similar to the Sierra set, so this is primarily a cosmetic upgrade for those who prefer blacked-out styling over traditional chrome.
2. Nilight Chevy Silverado Tahoe Suburban C/K 1500 2500 3500 Replacement Headlamp
This kit from Nilight is aimed at the older generation of Chevy/GMC trucks, specifically the 1994-1998 “OBS” (Old Body Style) era. Nilight is a well-known name in the budget lighting space, often regarded as having slightly more consistent quality control than other entry-level brands. This assembly maintains a factory-correct chrome and amber look, making it perfect for restorations or simple replacements on these classic trucks. If you’re working on a C/K 1500, Tahoe, or Suburban from the mid-90s, this Nilight kit is a direct competitor and a worthwhile alternative to consider, potentially offering a better balance of price and reliability.
3. AS 2002-2005 Dodge Ram 1500 2500 3500 Headlights Chrome Pair
Targeting the popular 3rd generation Dodge Ram (2002-2005), this two-piece assembly from brand “AS” focuses on providing a clean, OEM-style replacement. Unlike the four-piece kit for the GM trucks, this design integrates the main headlight and turn signal into a single large housing, typical of this Ram generation. This could potentially lead to better sealing with one less seam to worry about. For a Ram owner of this era whose only goal is to replace faded or damaged factory lights with something that looks brand new and functions adequately, this chrome housing pair is a direct, budget-conscious option that sticks to the original design language of the truck.
Our Final Verdict: A Cosmetic Upgrade with Serious Compromises
So, should you buy the DNA MOTORING HL-OEM-SIE99-4P-CH-AM Headlights? The answer depends entirely on your priorities. If your primary goal is to erase a decade of aging from the front of your Sierra or Yukon for the absolute minimum cost, and you’re willing to accept significant compromises in build quality, durability, and actual light performance, then this kit delivers on that one specific promise. It can make your truck look dramatically better from ten feet away, and for some, that’s enough.
However, we cannot recommend this product for anyone who relies on their truck for daily driving, especially at night. The poor beam pattern, ineffective high beams, and non-functional adjusters are legitimate safety concerns. The flimsy materials, susceptibility to breakage during installation, and poor weather sealing mean you may be replacing them again much sooner than you’d like. This is a classic case of “you get what you pay for.” It’s a cosmetic part, not a performance upgrade. If safety and longevity are high on your list, we strongly advise saving up for a higher-quality set from a more reputable brand. But if you understand the trade-offs and are simply looking for a cheap, temporary facelift, you can check the latest price and see if it’s the right compromise for you.
