I Installed a LED third tail light on my 2007 new body 1500. Brake light works but the back up lights do not come on. checked the fuses best I could. not sure if there is a fuse under a different name thats not obvious. I also ordered a new third tail light incase the first one was faulty and same outcome. brak light work but no backup. the normal tail lights work fine and they are LED. its a plug and play item so there is no way to install wrong.
