The light cases came in a timely manner. I had no problem installing them, using a video from Youtube.
The only defect I found was that a clip in one of the running lights would not compress, due to plastic the manufacturing process had failed to take out. I could also see evidence of one other plastic area that had been grinded down. After I removed the plastic with a sharp knife, I had no further problems installing the lights.
I do have one recommendation: I replaced my lights due to the plastic oxidizing inside & out due to sun & weather. I bought a can of "Plexus" marine plastic polish & protectant to treat the headlights before I installed them. You might want to recommend using a protectant prior to and after installation in the description or elsewhere. My pickup is a 2004 year model & I'm hoping I never have to replace the light cases again. Thanks!

Couldn't be happier
Made the truck look almost new again; and great to be able to see well at night. Since the hazing of the originals appears over time, I didn't notice how dim the lights really were. Piece of cake to install new ones. Good fit. Washed the dust off old ones and sold to a salvage lot' beats sending to the landfill. Shipping and packing on new set was top notch. I recommend highly.

I just saw your e-mail,
Which gives a chance to tell you.
The top lights work great, however the bottom ones
accumulate a lot of condensation and water.
I installed them correctly. I don't know if you
will do any thing about it.

Leak in headlight
I bought my boyfriend a new headlight set from you guys and one of them somehow has some type of crack in it or opening that allowed water to get inside of it and it is now permanently foggy on the inside due to the wetness that got on in the inside. We noticed this about a month ago and was waiting to see if it would go away but hasn't. Not sure if this is a normal thing to happen but kind of disappointed that it did. He called and talked to someone but they weren't very much help so he is going to be calling again for a replacement. Other than that, they look great and work well.

Replacement for old water leaking headlights
I have a 2004 Silverado 2500HD. These headlights are excellent replacements. On one of the parking lights, I had to file a little on the tab opening in order for the original light socket to fit properly. Otherwise a perfect fit and excellent price. So far, no leaks.

Product looks good.
Put extra silicon around seals. We will know more in a few month if moisture gets in.

Why did I wait?
in the past, I have bought almost every product available to clean the headlights of my Silverado only to have them get hazy months later. I did some quick research and found how easy it it to just buy new ones and install them myself. Helpful hint, replace all bulbs while the light are out. Not sure how long these will hold up, but they went in easy and look great.
