The headlight in the Vespa burned out earlier this week. Ordinarily, I've never been intimidated by replacing a headlight.
I am now.
In order to replace the headlight, I basically have to take the whole machine apart. I need special tools to do it.
Note to engineers - don't make regularly replaced items impossible to get to.
So, according to what I've read, I'll have to take off the mirrors, take off the Vespa badge on front, remove the horn cover, then locate and remove a hard-to-get-to screw, unscrew a few more things, then essentially pull the entire handlebar fairing off. Then replace the stupid bulb and put it all back.
