So when I got my 2003 Chevy, it was slammed, about 4 inches from the ground. But the last person put a bunch of money into putting Cadillac lights in it, the long skinny ones. But I took those out and put stock taillights back, but the reverse isn't working. I've put new bulbs in it and have checked the fuses. Anyone have any ideas

 

Ok dumb question, were they working with the cadillac lights??

 

Nah. Didn't have reverse lights in those haha. The people just put tape over them and had them in the lights.

 

Id start with fuse and make sure the nss is sending the signal, and see if you have power and griund at the light socket in reverse

 

Neutral safety switch on the trans controls when the reverse lights come on. I had to replace mine to get my reverse lights to work.
