ok i have two answer's for ya! for the price of one....
bad ground, it is best to run a ground strap from both tail light bucket's to the body to create a comon ground, also grease all conection's with lubraplate to seal out water and corrison.
you need to check the bulb's, if you are not useing the right one's or thay have been made wrong you will get this. there is a candle power rating for all bulb's, and tail light's/turn signal's should be 1157. back up light's and running light's are 1156 i believe.
on the 1157 the brake/turn part is brighter than the running part. if you managed to install them backward's, they have to offset nub's for alienment, you reverce the part you use for running to the part that should be the brake/turn signal.
