From cloudy to clear in minutes
After polishing my OEM lens for 30 minutes, then having them cloud up again jn a couple of weeks, I decided to swap out the entire units. 1A Auto had a great price on these replacements and it was a good move. They were swapped within 15 mjnutes TOTAL TIME for both! Now, the truck looks almost new again.

Replacement parking and headlights
I appreciated your installation video, which referenced my exact vehicle. (This was the main reason I choose your company.) One of the parking light socket holes was a little too tight, so I took some emery cloth and enlarged the opening slightly.
