I built my MB with the idea of being able to ride it on public streets with as little hassle from law enforcement as possible. Nevada law requires that a motorized bicycle be equipped with a headlight, horn, brake lights, tail light, and turn signals. I found a very inexpensive device (about $7) on ebay that does everything except the headlight. It uses LED lights, so its nice and bright. The headlight part of it is useless, so I have a separate headlight. It has a nice beeper that sounds when the turn signals are in use that can be heard over the engine sound, so it reminds you to cancel it. Ebay also has a bicycle "computer" speedometer that is a fantastic deal for about $3! It does tons of things- speed, distance, time, etc.
I think that its a good idea to check what your state requires and try to comply with it, it just makes us "good citizens" and lets us spend $ on new parts, not fines.
