I have a stock 89 Wrangler and when i push on the brake sometime my brake lights come on and sometimes they dont. I still; have the box lights as well and there most likely factory one to. When i turn on my head lights the lights in the back work as normal but still not the brake lights half the time. Its about time for inspection and i dont think i can get this ole beast on the road unless the brake lights work. So any help will be greatly apprecated ( cant spell sorry )
