I am very happy so far with this product. First because original headlight for my TLZ Chevy is about $1,200 each. I got them both for less then $300. They don't look as "sexy" as the original but "sexy" is over rated in this instance. Replacing them was easy but I didn't know they came w/o bulbs so if you ordering this light make sure you check your old bulb to see if they are still good and if not make sure you get some new ones. Also the bubs are not the same. The uppers and lowers are different bulbs. I didn't know all of that ahead of time and still waiting for the lower ones (should be arriving today) since my old light broke whey I hit a shopping cart in a parking lot. I couldn't use the old once. Overall they look great and fit very tight. The seals on the cap seem to be okay. Time will tell. We haven't had any rain yet so I'll have to wait and see. I recommend these over the original parts for one reason. No one should support the over priced rip off companies who think that just because they have there name on it they should charge 6 times more for an 8 year old truck. I wouldn't be surprised if the lights are made by the same company in the same facility from the same materials. I couldn't see and difference between the original lights and the off market ones other then the look indie the light. I could have gotten a different design for even less but chose those because the reviews were great.
