Led tail help

[Fred 4/6]

Buddy sold his truck so he sold me his led tail lights. He got them for 03-06 chevy/gmc. My truck is an 01 with drl delete. Needless to say the tails have been going crazy since I've put them on, one min while driving with lights out all is well, driving around with lights on and try to turn lanes lights go crazy, and sometimes only one side goes crazy... any help to fix this would be gratefully appreciated

You need load resistors on the led's they sell them at autozone.

is it just bulbs or a whole unit? if its just bulbs, you will need resistors, if they are complete lights, they are probably f^$ed

If you mean bulbs as in the ones you just plug in then no its a whole unit... but they worked fine on his truck. You don't think it has anything to do with the different years?

tails said they were made for 03-06 and you put them on an 01?

 

[Fred 4/6]

Yeah.. buddy had them so I figured why not.

it could be the different years, since they did change quite a few things from the 99-02 to the 03-07c
