You can always turn on, then off, your regular "night time" headlights, and they will replace the DRLs which should be on during normal daytime driving.
FWIW, the customary method used by "most" professional truckers is to turn headlights, or DRLs, OFF when the passing vehicle is clear to return into the lane of the vehicle being passed. Essentially, the
absence of lights equates to a vehicle not being there. This is especially preferred at night because flashing the lights from low to high "can" have a blinding effect on the driver looking in his mirrors.
Some coaches are equipped with an "ICC" switch which flashes off any lights that are on, or turns on those that are off. My Newmar had such a switch and I used it to signal my thanks when I had passed a vehicle which had signaled me. Unfortunately, the ICC switch did not affect the DRLs .
I solved the problem of how to momentarily turn off the DRLs by simply pressing very lightly on the foot applied parking brake pedal. NOT enough to engage the brake, but enough to turn off the DRLs. You will be able to see the dash IP symbol for the DRLs go off when you do this, and they will stay off as long as you hold slight pressure on the PB pedal. I've done this 1000s of times with no problems.
Hope this helps, Ed
