high mount third brake light
 
has anyone else had problems with their high center mounted third brake like on their wk? this is the third time i have had to take mine apart because the harness keeps coming loose and the light goes out randomly. it will only work every few times i brake. i tighten the harness and then it works fine for a few months and then it goes out again.

I just replaced mine. But mine was the Actual Light assembly. The old one kept Dimming as I pressed on the Brakes. I just replaced it from j4j.

Hey, Swede (from another Swede), I had the same problem with mine. I kept thinking it was the harness too. Finally, I decided to spring for a new light (about $35) and that solved the problem. I also installed the intelligent brake light flasher on it at the same time: http://www.comagination.com/bflasher.htm. Great to have to keep the guy behind you awake. I've got them on all my newer rides.

i took mine to a mechanic last year and he stated that he tightened the harness and it worked for a year. you think buying a new one would solve my problem? i am pretty sure the blinking brake light is illegal though

Don't know, maybe different states have different laws on this. I got the 4 flash unit. It actually flashes 5 or 6 times though and then goes on solid. I've had one on my other vehicle for almost 6 years with no problems, and no contacts with Johnny Law.

For the price, I think I'd give a new one a try. I fought mine for about 6 months and swore it was the wiring. I think there is something in the solid state circuitry in the light that causes it to be intermittant. All I know is after I changed it the problem went away. After replacing it I used to check it daily, and I still check it about once a week.....push the brake pedal in the garage before opening the door.

haha thats how i check all my lights everyday. i bought scotts extra light and i really hope it fixes the problem. it has gone almost a year with out going out so i thought i was in the clean after the mechanic "tightened the harness"

So my Girlfriend just informed me that my third brake light hasnt been working for a few months now.... yea shes just telling me this now so I had her sit in the jepp and press the brake while I looked at it and I hit it and it started working then today I checked it again and it stopped working so would buying a new one work or do you guys think its a wiring issue????

It can really only be one of two things:

- wire harness is not clipped on all the way. You need to hear a click when attaching it. Check the inside of the plug and make sure both pins look straight and nothing is shorting out (metal on metal).

- The actual light needs to be replaced. They are super cheap, just hunt around online or go to your local stealership and pick one up.

Had the "loose" electrical connector problem on my 05 JGC 3rd brake light....started about 2 years ago. Secured the plug in a bit snugger with wood toothpick shims, confirmed light went on before remounting, put a couple drops of SuperGlue on the wood shims...still working thus far. New lights on eBay for about $30.00 if you want to go that route.

its probably a loose pin at the circuit board... properly repaired with a replacement assembly. I have never seen an inop 3rd brake lamp that wasnt repaired with a new assembly.
