do i need to disable DRL for both high and low beams ? how do i do this ?

 

You only have one...either your DRLs are low voltage high beams, or theyre youre lowbeams. Theres quite a few threads on disabling your DRLs...but it's all dependent on what year blaze youve got. Also check the related threads below...like I said, its covered pretty thouroughly

If youre still confused, post up!
