I'm about to purchase a new folding bike which I will be riding a lot after dark. Being an electronics geek, I'd like to make some kind of led contraption to make the bike more visible and stylish at night (I already have a good headlight system).

I'm still working out the details, but I would need a handlebar mounted switch to turn the lights on and off. After looking around on ebay, I saw some motorcycle switches that looked cool. Does anyone know if these would these fit standard bicycle handlebars?

(also, feel free to link any cool led mods I could use as reference.)

Thanks.
