DRL DISABLE MOD - This relay kit will disable the Daytime Running Lights (DRL) while still allowing the auto headlight function. The relay is spliced in at the bcm and will disable the DRL, along with keeping the auto headlight function, but It will also disable the low beam's night time perimeter lighting function while remote lock/unlocking. Disabling the DRL is beneficial when installing HID low beams as the pwm signal of the DRL decreases the life of the ballasts. This kit will work in several '02-'09 GMT 360/370 vehicles (Chevy Trailblazer, Gmc Envoy, Buick Rainier, Olds Bravada, and Isuzu Accender)
 
 
 
DRL FOG MOD - 
 
This relay kit will convert the Daytime Running Lights (DRL) from the low beams (factory) to the fog lights. This mod keeps the auto headlight function, so when it gets dark the fog lights will turn off and the headlights will turn on. In addition to the fogs being on during the day, they will also become the front night time perimeter illumination while remote unlocking. This kit will work in several '02-'09 GMT 360/370 vehicles (Chevy Trailblazer, Gmc Envoy, Buick Rainier, Olds Bravada, and Isuzu Accender) with factory fog lights.This is for vehicles that have factory fog lights only.
