I have an upcoming install to do in a new GMC. What are the choices for wig-wags? Can the DRLs be flashed without screwing up the computer?
We're looking at an Edge bar, hideaways in the taillights, LEDS behind the grille, and wigwags either in the headlights or DRLs. Anyone have experience with this model?
I've searched the forums and got conflicting views on this, figured the best bet would be someone that had actually done one. Thanks.

i would go with some hide a way halogens

Just install it like the DLR's arnt even there, since they are entirely separate from the headlights and highbeams... Hope this helps
