There are about 4 or 5 very small bumps on it that you can only see if you are an inch away from it or feel it. I have no idea where they came from. I sanded is smooth with 400, 3 coats adhesion promotor (10 minutes between), 4 coats paint (10 minutes between), waited 15 minutes after the last one, and 4 coats clear (10-15 minutes between). I know I should have sanded, but I was slightly in a hurry (plus I was painting while I was doing my lights).
I finally got my money back. Well, most of it. Hidlightsusa.com took 12% of my total (not including the original shipping) for a "restocking fee" which I think is total BS, but they originally wanted 20%. So I ended up loosing $13.99 in the original shipping (which at least $10 was pure profit for them), $9.23 to their "restocking fee", and $10.60 in shipping the bulbs back. So I lost $33.82 in the whole deal and nothing to show for it. This is why I never buy without seeing and knowing it will fit and work!
My final advice:
Only buy LEDs if you HAVE TO HAVE THEM. The cost VS benefit sucks.
Buy them from a source that someone else already has (like superbrightleds.com).
You get what you pay for. The bulbs I bought were half the price of SuperBrightLeds.com and I obviously got what I paid for.
They are no where near as bright as regular bulbs. My backup lights are so much brighter with the regular bulbs back in (new, clear tail lights help too).
The only thing I might ever buy LEDs for is my backups just so they'd match the light bar. At that time, I'll pay more to get something that fits right.
I just hope someone benefits from my $34 experiment .
I have a 1997 chevy s10 SS that I am trying to convert to LED exterior lights. I have changed out the front bumper light/turn signal as well as the rear break/turn signal bulbs with LED replacements. Now when ever I try to use my turn signal(either right or left) the truck acts as if I have activated my hazzard lights. Both left and right dash lights flash and all 4 exterior lights that I changed all flash.
The bulbs that I am using are Pilot 3157/3057 replacement bulbs. Any help or suggestions would be great
