What does drl-1 daytime running lamp module do?
The DRL-1 Daytime Running Lamp module provides a fully automatic Daytime Running Light function by operating the vehicle’s front directional signals steadily, except when they are flashing as turn signals. This DRL implementation complies with US and Canadian DRL performance requirements, and has major advantages over headlamp-based DRLs.
Which is the daytime wire in a headlight system?

The system is activated when the ignition switch is in the ON position, the headlamp switch is in the OFF position, and the parking brake is released. What it means: The DRL “Module” does everything.

Can a drl-1 be used as a turn signal?
The DRL-1 module can operate in either of two modes; you decide whether you want the left lamp to remain lit steadily as a DRL when you are signaling for a right turn (and vice versa), as is the case with factory-installed turn signal DRLs, or whether you want the opposite-side DRL to extinguish when you are signaling for a turn.

Other cars the fuse will not deactivate the fogs and auto “ON”. 1999 and 2000 more likely to have the “auto on” feature, related to the GM liability for no tail lights at night. On some newer GM models it may be possible to press the “Dome Override” button 3 or 4 times within 6 seconds. This will disable the DRLs while the vehicle is running.

Can a DRL switch be removed from a headlight?
Presumably the spring that returns the headlight switch to ‘DRL’ (from ‘off’) could be removed from inside the switch and you would have a normal headlight switch with DRL’s optional yet fully functional if you left the switch in the ‘DRL’ position. Unfortunately, this is not the case.
Is there a way to disable the DRLs on a GM Truck?
On some newer GM models it may be possible to press the “Dome Override” button 3 or 4 times within 6 seconds. This will disable the DRLs while the vehicle is running. When it is restarted, the DRL function will reset to “always on.” We’ve heard that this works on full-size and S-series trucks.
