there should be two screws that hold the tail light cover over the bulb (red) take that off and and then just take the bulb with you to a parts store it would most likely be a very common bulb they would have in stock

READ THE OWNERS MANUAL

You may have a fried fuse. Look in your owners manual to find out which fuse it is in the fuse box diagram. If that is the problem make sure to use the same amperage fuse to replace the burned one with. I fried fuse is usually a sign that you have a short somewhere. But they can also fry for other reasons such as excess moisture somewhere. Sometimes they just burn from age and fatigue. It may solve it to just replace the fuse, but if there really is a short, the new fuse will fry too.

I have a1999 FLHRI and I install a led tail/brake light bulb and it caused my cruise not to work. When I changed back to stock my cruise worked again check your taillight bulb.

Open trunk and remove the back trim panel (4 vinyl screws/nuts), underneath you'll find access to your tail lights - remove those nuts and you will have access to the bulbs.

Hi

Such and early model, the lenses should unscrew from the outside and take them off and replace the bulb. If not there will be reataining screws behind the lights which will relaese the light unit and hey presto.

did you check the grounding points? if you have access to the wire diagram that would help. try measuring power at the fuse first. if theres power there then try the bulb socket. if theres no power there then you have a wiring problem.

check you tail bulbs as you have a broken circuit
