Warden...there's a little bulb that illuminates the orange colored circle on your headlight knob. You just carefully pull it straight off to get access to it...I've tried everything to get it to work...Like I said, the wires all contacting the switch look good and clean...I can't get any power to it with a tester. And yes, I am turning the headlights on, then plulling the knob off to do this testing. I didn't know it had one either until the other day. I was driving an older 450SL and noticed the switch illuminating...hummm...

any ideas...?
