Having a weird issue with my 96 XJ. I recently purchased some LED taillight bulbs. I do not have any other LED bulbs in my set up yet. When I put them in they worked perfectly fine with the running lights(side marker lights and turn signals) on and the headlights on as well. But when all the lights are off and I hit my brakes, the front sidemarker lights and turn signals come on plus the rear sidemarker lights as well. Has anyone ever come across this before? If so, how did you fix it?

 

put the normal bulbs back in. does this fix it? if yes, get different LED bulbs. i ran some a while back that worked fine.
