3rd brake light with 5 halogen
I have a convertible with the 5 halogen row for a 3rd brake light. It wont come on. I checked the V at the hatch/trunk contact and I have 11.7V and then I tested it at the connector to the light strip and again, 11.7V. I then connected my light strip to the battery and it lit. It just wont light at the trunk and I have cleaned the terminals really well. What could it be?? Do the halogens need more juice? At the battery they were on 12.3V.
I cant figure this out. Odd.

Re: 3rd brake light with 5 halogen
Okay, so I put some wire into the socket for the 3rd brake light. routed + to multimeter, - from meter to a bulb, then other side bulb back to - of socket.
Meter says 11.85V and bulb does not turn on.
This is same as last night. I have voltage on my meter but it would not light up my 3rd brake light assembly. Very odd.

Buy the bulbs at Radio Shack, much cheaper than anyplace else.

Re: 3rd brake light with 5 halogen
I also sell the bulbs if it turns out that is the problem. Before replacing them, I'd spray the bulb sockets with some deoxit of equivalent contact cleaner.
Also are you sure the contacts on the spring-loaded bar on the underside of the hatch are in good shape and not bent or missing? I've seen both conditions. Look at one on another car another or post your picture of the spring-loaded bar. Also if the hatch is out of adjustment (pushed to the rear of the car) the spring-loaded contact on the bar might not be making proper contact with the contact plate on the top of the rear plastic hatch surround piece. You'll need to realign the hatch to correct this.
A word of caution to everyone. NEVER touch the halogen bulbs with your fingers. The oils on your finger wil cause a hot-spot on the bulb and it will burn out quicker.

I stock both 10 and 20 watt bulbs for the application. $2.95 each. You can determine the total cost before committing to purchase. Put the items into your shopping cart, then click on "shopping cart" on the upper right, then click on the lower left of the screen under "Estimate shipping & taxes" and select the shipping method you prefer.

Re: 3rd brake light with 5 halogen
Actually they will ship to you by USPS Priority Mail Small Box Flat-Rate Int'l insured. Let me calculate the actual S&H. I used to ship First Class Int'l, but they've lost 3 packages on me recently and USPS won't allow insurance or track First Class Int'l. E-mail me your address.

I just did the calculation via my web site. It is $54 if you chose the quickest mehod (Express Mail Int'l). I see Priority Mail Int'l is $37.65 USD. I'll have an estiimaate via USPS site shortly

Re: 3rd brake light with 5 halogen
there is tracking on 1st class intl, it's the number ending in "US" They always say there is no tracking but there is.

Re: 3rd brake light with 5 halogen
I am not shipping ANY orders via First Class Int'l any longer. I can't afford the charge-back for the cost of postage AND the cost of the product AND the hit to my reputation when USPS or whoever they contract with in your country loses it.
Still waiting for your address.
