Tail lights not working

[cghamm117]

Last night i got pulled over by a cop for my taillights not working. Just bought the truck so he gave me a warning. All the fuses look good im not good with electrical so im going to be in trouble i think. If anyone has any helpful hints to possible problems it would be appreciated thanks. Also every light works excepts for running tail lights. The headlights, brakelights, turnsignals, hazards everything is good except tail lights.

I would start by checking the bulbs themselves. The brake lights and turn signals use a different filament than the parking lights. If the bulbs are good, then you will have to start checking wiring.

I had recently had the same problem, If your bulbs are good, and you are 100% sure you've checked your fuses and they are good, before you start wire tracing... I recently had an aftermarket radio installed, good ol' best buy wired the "orange" dimmer light wire, that is located on the back of the radio wire harness (its there for radios with color changing options) my radio did not have that, therefor it threw a negative signal and acted as a ground, leaving me with everything except running lights. It took me 2 weeks to trace that damn wire... hope it's easier for you, good luck!

I don't think it will be as bad as you expect.
