After weeks of putting it off (and looking in the wrong place for replacement bulbs), I hit Fred Meyer's last night and bought a new headlight bulb to replace the blown out one -- the replacement procedure looked pretty straightforward. It did mean removing one piece of the engine but it was just a reservoir for windshield washer fluid so, not *dangerous* to screw up with at least.
What the manual didn't mention was that while removing that piece technically allowed access to the headlight assembly, it involved sticking your hand into a tiny roughly hand-size opening and squirming it around under an overhang, squeezed between the battery and... some other stuff that wasn't as recognizable. Meaning that (a) I had no leverage, and (b) I couldn't see what the heck I was doing.
There were a couple points in there where not only was I not sure I was going to be able to finish the replacement, I wasn't sure I was going to be able to put all the bits back into place at all. But after taking 20, I managed to get everything in place. And it hasn't exploded yet.
Since that was the first headlight to burn out in the 20 years I've been driving, maybe if I'm lucky I'll die young enough not to ever have to do it again? Oh, who am I kidding, I'm sure my clumsy fumbling got a speck of dirt on the bulb and it'll explode as soon as I leave the lights on for more than fifteen minutes.
