Yesterday I had the bike all ready to take to inspection. I just needed the tires. So I removed the wheels off, and right now they are in the shop. I am tweaking a few things. I turn on the bike, to test all electrical stuff. Evything works except the brake light does not go on. The light is on, but when you push on the brakes it does not light up anymore to signal stops. My question is. Do the wheels need to be on the bike in order for the rear brake light to work. Front and rear are not working.
