Default 1995 REAR BRAKE LIGHT NOT WORKING

I guess red is for stoplight, yellow for runninglight and black for ground.
No...I haven't been able to yet. I've been busy with doctor appointments for AFIB and Lung Cancer treatments. I'll get on it as soon as I can.

I unplugged the 2 wires from the brake light switch. With my probe light, I turned ignition switch on and with both wires removed from brake light switch 'both' wires showed power to them. I thought that the brake light wire should only show power when brake pedal or front lever was pressed. Am I wrong or is there something wrong with the wiring? Plus now the front right turn signal light doesn't work

Here's how to check:
1. unplug the O/W wire from your stoplight switch
2. Connect probe light clamp to ground at frame
3. Turn ignition on
4. Check with tip of probe light if you have power at the O/W wire. If you have no power check if you have power at the the acc fuse outlet where the O/W wire is connected

5. If you have power at the O/W wire at the stoplight switch unplug the R/Y wire at the switch, apply the brakes and check if you have power at the stud where the R/Y wire was connected. If you have no power you have a bad brake switch. If you have power, reconnect the R/Y wire, apply the brakes and check the R/Y wire at the rear light connector for power. If you have no power, check for a broken R/Y wire. If you do have power the led module went out of order.

I had a "Harley Brand" LED taillight on my 05' Wide glide that had LED's go bad one at a time in a very short time. I replaced it with a Bright *** Light and never had a problem afterwards!
