not 100% sure but PIAA makes some that look similiar. I saw a kit they make switch,wiring and all that mount lower on the forks like where the fender mount bolts or the reflector bolted on and they really worked good. the guy on the bike they were on was coming up behind me in the daylight and you really took notice of the bike/rider.
You could get some Kuryakyn Large Silver Bullets, because that's what those look like. With some Kewl Metal mounting brackets you'd be all set! I'm sure that Hal sells both. Click on the Direct Line logo at the top of this page. :bigthumbsup: :doorag:
