i bought a headlight extender for a VTX moved the headlight out 2" and down 1/2" cost about $30.00 if i remember. do a web search. went with a 12" windshield no probs.
Oops! here it is for $35.00
http://glensvtxgarage.com/headlightextension.htmlyou could put the light under the mount and add spacers to drop it even further. this setup also brings the light out flush with the front of the fairing for a cleaner look.
ps: you'll need to cut off the headlight supports that hook to the turnsignal mounts, also you'll be removing the turn signals as the will not fit with the fairing and lowering the will cause them to hit the radiator and brake anyway.
i used a HD lightbar from a FL model with matching spots and turns( really freaks out oncoming HD riders)
