yesterday I was trying to wire up a new brake light on my 05 vulcan. I bought a brake light from the auto store and hooked it up, but no matter how I connected the three wires all it would do was either stay bright, or dim (i.e. the running light, and the brake light) depending on how I wired it up. well in the process of trying to figure out the brake light I blew one of the fuses. I replaced the fuse and now the stock tail light comes on (running light) but the brake light only engages when I use the foot brake. The hand brake does not engage the brake light at all, and my headlight will not come on. I checked all of the fuses and they're all good. is there any reason why the handbrake would not engage the brake light while the foot brake does? and what does that have to do with my headlight? I'm really confused about this and any help would be greatly appreciated.
