I just put led bulbs (and resistors) in my rear taillights. Now when i step on the brakes my front parking lamps and fender bulbs turn on. Anyone run into this problem before?

 

Does the lights act normally when you put your stock bulbs back in?

 

yes they do

 

LED bulbs use very little power compared to stock bulbs. You are getting enough feed back through the wiring from you brake lights to light the LED bulbs, this is probably due to a ground wire that is improperly installed for one of the tail lights. The current returning to ground from the brake lights seeks the easiest path to ground and that is through your lighting harness and the LED bulbs.
Good luck in finding the bad connection.

 

i checked all the wiring and all the connections are good. Im thinking the led bulbs are bad themselves

 

Not likely. Check were the ground wires tie to the body or chassis, should be a stud near the tail lights with a few wires and a lock nut on them. Loosen these and make sure they are clean, both the contact point on the body and the terminals themselves, then reinstall.

 

Use a jumper wire and from the back of the light socket neg side jump to a good ground. That will tell you if that is the prob, and which side it is

 

didn't I have a post on here detailing exactly what product was needed? where did it go?
