I wanted to second the Cyclops products. They are very visible and easy to install. Other parts on this forum have the wiring accessory plug you can use for easy switched installation. I tapped the low beam circuit for switch power so you can't turn the lights on without the bike running.
The only thing I want to do in the future is shorten all the wire runs I have inside the bike, I just left all the wiring and coiled it up nicely but that really crowds the space and looks horrendous. I think if I get a portable soldering iron and some nice hardware/connectors that would be another weekend project; cutting off all the excess looped up wire.
