Brake light not working on 2009 harley classic

SOURCE: changed to led from harley and now i have tail light but no brake

Did you check the bulb? and wiring?
good luck!

try starting with the bulb. brake light bulbs are dual fillament, meaning you have 2 bulbs in one basicly. if your brake side has blown then the tail light could still work. Or try checking the brake light switches, one on front brake and one on rear brake pedal. to test switches disconect wires and join them together with small bit of wire or paper clip. this will make the light come on meaning you have a bum switch.
if you have only been using the rear brake, that has an adjustable switch, may need to mess with it

i wouldnt ride a bike with the brake lite on - get it taken care of

SOURCE: 2005 harley ultra running lights quit working

I would check my wiring

Check the wiring within the headlight shell--look for connectors that may be corroded or pulled loose. A little WD-40 will favor connection integrity when sprayed into the connectors, then coupling and uncoupling them several times. Hope this helps!
