Lights Out

I replaced all the exterior amber and red camper lights in front and rear. When I plug into my truck...none work. The porch lights and tail lights work fine. I wired everything exactly was it was with new lights. Each light has green on one side and white on the other. The bulbs have 2 black leads. Is it possible they are flipped? There is no marking +/- that would make me think they polarity matters. I am thinking it does not. What have I done wrong? If one light has a bad connection - is it like the Griswald scenario and none work? :?

  • I am pretty surer its 12V. Does not really say. Looks identical with same bulb as original.

  • Welcome to RV.net!
    The center point on the lamps should be the 12 volt source. If you bought the small plug in type fixture, it should not matter.
    The porch light should be connected to the TT battery.
    There should be a junction box under the tongue of the trailer. Check there for problems.
    What is the clearance lights using for ground? Some rigs use the metal skin as the ground return.
    What is make and model of TV, TT and lights you are using?
    Some TVs have individual fuses to power turn signals and taillights. Some have the fuses under the hood.
  • I would measure the voltage at the lights. You did use 12 volt lights?
  • Did you put in LED's? They are diodes. They only work in one direction. Try changing the leads on just one and see if it works.
