Haven't tried this yet, but fairly sure it will work. I have an old motorcycle turn signal I plan to use as a brake light. Here is how I plan to activate the light when braking. First, the body of the light is steel. Its the old bolt-on type. I have already drilled a hole in my luggage rack, so the light will be grounded to the rack. I plan to power it with 4 aa batteries in a battery pack. I will wire the light to the battery packs lead, then I will connect a longer wire to the battery packs ground so that it can be run up to the handlebars. My brake lever is an older style all metal type that clamps onto the handlebars with two screws.I plan to make a tab out of a piece of flat aluminum stock and attach it to one of the bolts that holds the brake lever in place so that it extends out parallel to the handlebar. I then plan to drill a hole in the brake lever itself, so that a nut and bolt can be placed through the hole. The nut in bolt is of the type that has a hole in it for a brake cable. I will feed the battery packs ground wire through it, thereby clamping the ground wire to the brake lever. I will insulate part of the end wire so as to make sure that the wire is not touching the lever. When I squeeze the lever, the ground wire will make contact with the tab that I put in place, thereby completing the circuit and activating the brake light. When I release the lever again, the wire will obviously break contact with the tab, thereby breaking the circuit and deactivating the brake light. Thoughts?
