I am too cheap to spend $900 + for driving lights. I bought the brackets from Twisted Throttle. $49.00. The large lights under the mirrors were $20 each. The small lights mounted on the forks were $16.00 for the pair and came with a switch. I used the switch to control the large lights and wired the small lights through a relay that is triggered by the headlights.
Just an update, I have been running these for a few weeks and they are incredible. The small lights were designed for daytime conspicuity; but their performance at night is what has really impressed me. The large ones under the mirrors simply bring day to the night.
