I have the same Moto Lites and love them. I just augmented the headlight with a Sylvania Silver Star bulb and now my friends who ride with me at night say they need sunscreen if they are in front of me.

And they dont bother oncoming drivers at all. You can wire them into the headlight nacelle right onto the aux light high beam switch. You can find complete instructions and pictures on the Thunderbird 1600 forum. Very simple.
