Z-OFFROAD LED Headlights Assembly DOT Approved with DRL Turn Signal Hi/Low Sealed Beam Side Marker Compatible with 2003-2006 Chevy Silverado Avalanche

These headlights are just amazing. Especially since they don’t cost close to 1k like others on the market. They look amazing and give my Avalanche a more modern look. Installation is super simple and the instruction manual couldn’t be more clear with not only text instructions, but actual color images of the installation process along with troubleshooting tips and full instructions on how to align them properly.Packaging: I would’ve sworn these were shipped from the GM factory. The packaging was great and kept the lamps perfectly safe even with how rough some delivery drivers can be. Also, the instruction manual is right there on top when you open the box. I cannot stress this enough. Take a minute to read the instructions to prevent any confusion while installing your new headlights.Build Quality: As soon as you remove these headlights from the box, you immediately notice a heavier and stronger feel to these than with any other standard headlight housings I’ve had before. All of the plugs are molded to the unit nicely and connections feel very solid. Nothing inside the housings rattled and the wiring feels strong, no worrying about breaking a wire while installing these.Installation: Installing these are a breeze. As long as you can read a label and plug connections in, you’ll have no problems. The instructions mention plugging each section in and testing it individually. Trust me, this will help in the long run. Each connection requires the correct polarity to function. Some of the plugs are actually labeled to show the plugs polarity. So for most of them I was able to pick out the black wire on my vehicle plug and line it up correctly the first time. For the DRLs I was having issues getting the upper section to light up initially. I tried swapping polarity like the manual states, but neither worked. After a few tries, I ended up chocking my wheels and putting the truck in gear to test them while I could hold the plugs. I’m not sure if my OEM plugs are just old or the connections on the new lights were just a little off, but I was getting a loose connection. I ended up having to slightly pull out on the metal connections for each plug to get a good contact that wouldn’t intermittently disconnect. I also would strongly suggest adding a dab of dielectric grease to each plug before finalizing your install. I need to go back a wrap some of the connections with something to add some moisture resistance. This is where I think some sort of rubber boot would have been great. The assemblies clipped into the trucks mounts perfectly and snug. The holding pins were a little tight to get back in, but it ended up making for a better final install to prevent any unwanted movement.Light output: These way outperform the halogens I’ve been running since day one. The light pattern looks great with full coverage and no annoying breaks in the light beam. You’ll notice that the driver’s side seems to have a dip in the light line. Apparently this is by design so you don’t blind oncoming traffic. The high beams are very bright. The only oddity I did notice is that the high beams do not spread like you would expect. It is tight beam straight forward but it gets great distance. I guess this is where a set of decent fog lamps would make up the difference.Moisture: As of now I’ve only had them installed for about a week and it has rained several times pretty hard and I have not seen any water intrusion into the housings.Bonus: The instruction manual states that you will need to install a flasher relay to prevent hyperflash which is typical, but on my 2004 Avalanche, I was surprised that I didn’t need the relay. The units flash normal right out the box.

My stock headlights on my 2005 Chevy 2500HD were cloudy and limited the light output making it hard to see at night. I found these lights and am glad I ordered them! They are great quality, have great light output, were easy to install, and look great!Upon unboxing, the level of detail and care are apparent. The lights were protected with thick foam on all sides with dividers between them. The instructions were clear and easy to follow with lots of pictures. The lights are plug and play, meaning no wiring skills needed. Test the light when you plug it in, as the plugs do insert either way, which may cause a polarity issue. If the light does not come on, flip the connection and it should work then. On my set, I plugged the connector in on the side without the polarity symbols (+/-).The only downside is the connection for the daytime running lights and the turn signals. The connection is not weatherproof. You may be able to find better connectors at a parts store to fix this issue.Once installed, the lights were definitely brighter than the stock headlights. There are directions in the booklet for correcting “LED hyper flash” but I did not encounter that issue when I was finished, everything worked great.These headlights appear to be well-made and durable. They are marked DOT-approved and have an adjustment screw to align them correctly once installed. They also include a roll of tape to aid in alignment and describe the process in detail in the instruction booklet.To conclude, if you are looking for a bright, durable replacement option at an affordable price, these are a great option.

I recently purchased a set of aftermarket headlights for my 2004 Chevy Silverado, and I couldn't be more pleased with the upgrade. Here’s a detailed rundown of my experience:**Installation:**The installation process was straightforward and took about an hour. The headlights came with all necessary hardware and clear instructions, making it easy even for someone with minimal mechanical experience. The fit was perfect, and I didn't encounter any issues aligning them properly with the existing mounting points.**Performance:**The improvement in visibility is remarkable. These headlights offer a much brighter and more focused beam compared to the old, stock headlights. Night driving has become significantly safer as the road ahead is now well illuminated. The beam pattern is even, with a clear cutoff line that prevents blinding oncoming traffic.**Build Quality:**The build quality of these headlights is impressive. The materials feel durable and well-made, with no signs of cheap plastic. They have a sleek, modern look that complements the truck's design nicely. Additionally, the lenses are resistant to fogging and have maintained their clarity despite varying weather conditions.**Value:**For the price, these headlights are a fantastic investment. They have not only enhanced the aesthetic appeal of my Silverado but also significantly improved nighttime driving safety. Given their performance and quality, I consider them a great value for the money.**Conclusion:**Overall, I highly recommend these headlights to anyone looking to upgrade their 2004 Chevy Silverado. They combine excellent performance, high build quality, and great value, making them a worthy addition to any truck. Whether for improved safety or simply to refresh the look of your vehicle, these headlights are a top-notch choice

These lights are amazing in all aspects.BUILD QUALITY is top notch! From material used on housing and lens to the wiring used. Only down side I could complaing about is the connections where they plug into the factory wiring, there is nothing to keep the weather (rain/snow/road salt) from getting in, so I used a generous amount of Di-Electric Grease at each connection.INSTALLATION was a breeze, although I did have to drill larger holes on right (passenger side) headlight for the securing pin. Everything was literally plug and play (I even got to get rid of my old resistors for anti-hyperflash from my old led headlights, these are built-in on the new ones). Test lights before installing them back in truck as you may have to flip some connectors if you notice a light not illuminating (change polarity).LIGHT OUTPUT is so nice, crisp cutoff lines, nice spread and great distance on high beams, easy to adjust height too.I had installed a new set of stock housing installed in my truck with all new led high/low bulbs a week prior to getting these ones and didn't thing I could have anything better, I WAS WRONG, these have better light output AND give the truck a touch of a modern look but go great with that old classic body style!I can not speak on the LONGEVITY of these yet but if anything changes I will update review.I HIGHLY RECOMMEND THESE LIGHTS!

Funcionan muy bien comparados con los OEM ya viejos de mi Chevy Silverado 2006.Son fáciles de instalar, el único problema que yo tuve fue con el arnés pero de mi troca los faros están bien hechos e iluminan excelente.Hay que calibrarlos siguiendo la guía que viene en la caja.

Wicked looking lights, easy install!

The media could not be loaded. I put these headlights on my 05 Chevy avalanche. Super simple install, all the cables were plug and play and came with very detailed instructions. Very happy with these lights they feel way better quality than the factory ones, and have the perfect amount of light output! Would definitely recommend purchasing these headlights!
