Here's a home made light mount that attaches to forks with V brakes. The headlight clamp was at a awkward angle on the handle bars so I mounted the light on the V brake stand off. I used a 1 x 1 inch L bracket and a 1/2 inch PVC pipe cap. You simply back out the screw on one V brake arm to attach the L bracket. I had to enlarge both holes in the bracket and filed off the flutes on the PVC cap. I painted the mount and added hockey tape to obtain a ideal diameter to match my light clamp. I had all of the parts on hand but they should be under three bucks @ Home Depot. While you're at the hardware store pick up a length of 1.25 inch ID foam pipe insulation. I slip the foam over my top frame tube and have no concerns leaning my bike against a pole to lock it up.
