92 Suburban Hi-beams don't work

Neither hi-beam works in composite headlights. Seems like three places where problems could be: light switch, low/hi beam selector switch, and the bulbs themselves. Seems unlikely that both bulbs would go. Any suggestions on how to troubleshoot?

Start with the links and posts below. If the vehicle is air bag equipped, time for professional service if you have to get into the column for any reason.

First try running 12 volts direct to the high beam bulbs to make sure you dont have 2 lights out. You may have been running on one high beam for awhile and not noticed it and then finally the second one blew.
