The plug on mine seems to be made backwards. I put them in where the plug clipped over the little lock thing and they didn't work. I turned the plug around backwards where the clip was on the opposite side of the little lock thing and they worked fine. Try flipping the plug around. Had mine in since Dec. and no problems. Hope this helps
Nice HiDS, i went to go to get them on my 06 sliverado and they didnt work, the installers said i had to order a piece because the electronics was acting like it was a burn bulb so they never worked! Did you have this problem?
