Mostly likely: blown fuse or bad bulb
there should be a fuse under the hood or under your fuse block that probably blew
All of these parts run on electricity, and for all of them to fail would be bad. Bad or burnt wiring could cause them not to work, or a alternator going bad could cause them not to work as well.
the daytime running lites go out when you put the trans in park. they also go out when you depress the parking brake. i would start looking there.
The cause is THE EXTREME DAYTIME IN DESERT. The effect is DRIVING ACROSS THE DESERT AT NIGHT.
Bulbs burned out?

Im Assuming you Should Check The Whole Lighting System. Usually it NOT the switch but could be. suprised me once when it was, but again usually not. The Daytime lights a separate from the Regular beams, check the high and low beams next before anything else. maybe just an old light that decided to Crap out?
there is a number of things that could cause this. here are a few easy ones to check. is the e-brake fully disengaged. are the bulbs burnt out. is the wiring harness plugged into the daytime lights bulbs and in good condition. if these check out, you may have a fault in the daytime running light module.
