Can I get some help? I have a 2014 dyna FXDL. I have an aftermarket tail light and the break light and signal lights are solid and wont blink or transition between the tail light and break light. Thanks!
Im having the exact same problem on my 2013 Ultra Limited. I dont have any aftermarket tail lights but i do have an aftermarket headlight and spot lights. I say this because when i put the ignition into acc. mode and press the brakes, all lights come on. Also if i remove the main light fuse (not the headlight fuse) and then press the brakes i can see the brake lights engage. I have replaced the main lighting relay as well as the brake light relay.
Any more thoughts on what this could be?
