My bulb-out light is without a bulb itself. It went haywire when my taillight fell out and shorted something back there, and I had to tap into the wiring on the other side to get the taillight to work again. So that's not a problem. I've worked as a truck-driver and a locomotive engineer, so I'm used to regularly inspecting equipment. I just do a walk-around every so often, and I check the brake-lights whenever I can see the car's reflection in a store window or SUV. &^)

What I'm thinking of doing is crushing a pair of half-out 9004's I have, then soldering the H-4 leads to the bulb leads, which would make a pair of adapters. The thing I've been trying to figure out is how to safely break the 9004's, since I know from experience that halogens can be reactionary. I'm tempted to put them under the front tire and just drive over them.

I'll post if anything wild happens.
