Just purchased a set of APC Retro 3D taillights for my 2004 Ram 3500. I can't get them to work properly. When I turn on the headlights the back-up lights come on with the taillights. Also the lamp out warning light comes on all the time when you use any light in the new housings. It looks like there is a box built into the new harness to account for the missing light ( uses only 1 3057 bulb for turn/tail/brake ). Please help.

You got an OLD set of lights send them back they will not work
