15. _________ _______ ________ (DRL) operate the headlights at a reduced voltage anytime the vehicle is running in daylight. Applying the parking brake turns the DRLs off.
ATASA 5 th Lighting Systems
Daytime Running Lights
Huge Safety Note The parking lights in front & the running lights in the rear are not on
if the DRL’s are on!!
ATASA 5 th Lighting Systems
Daytime Running Lights
16. Automatic lights use a __________ sensor that determines the ambient light level & automatically turns on the headlight system if surrounding light is too dim. (dusk, in a tunnel, cloudy, etc.)
ATASA 5 th Lighting Systems
Huge Safety Note: Parking lights (front) & running lights (rear) are not on if DRLs are on!!
