Dear All, I'm a newbie here,
I'm a optical designer of automotive lights,
We're developing aftermarket and performance headlampsfor 2006 Malibu,
so I have a question about DRL on 2006 Malibu,
When , I mean on what condition will the function turn on?
and is it the turn signal or the low beam or high beam operates as DRL?

Thanks so much for your kind answers.

 

The pcm controls the drl. it comes on automatically or they wont work if you pull the fuse out.
