First orginal bulb just brake light out.

What is causing this problem?

Check you voltage, check for water in and below blub in trunk. i read where car had this problem water in housing and got into lock pump and caused fire, i have seen some xfires on line where it appeared that fire started in taillight area area.i also found where a jumper harness having resistance that drops the volts by 1 2003 merecedes repaired this. also check the blub holder mined melted not getting go contact keep replacing blub replaced socket. also google about brake lights
Re: Keep blowing brake bulbs
Thanks for the suggestions. The car is completely stock, so no rewiring and this was with three different bulbs. They light up for a split second then blow out. I'll have to get a volt meter and check the voltage going to the bulb. Also there is no water or moisture in there that I can see.
Thanks again for the help.

Did the actual brake light or rear light go on and be witnessed by someone?
These are dual filaments of different wattage and some have installed them wrongly somehow and had tail lights go on when they put the brakes on but no brake lights.
Over voltage would appear not to be the cause as other lights would suffer as well.

Did you do any rewiring lately? Thats about the only thing I can think. Does any other system or systems go out when that bulb blows? That would be a clue to where to look. If it only happened once I would replace the bulb and keep an eye out on it. You can get a bad bulb sometimes.
If that was possible then you could bump it up very high and be a real danger.

Well, he didn't say 'voltage', he said 'current', but that is wrong anyway.
You CAN blow a bulb with too much voltage, but all that is available is 14.7v,
but there is no way to force more current through a bulb, it is, after all, just a resistor.
I would look for a loose connection, either B+ or ground, because high frequency voltage changes CAN blow a bulb due to the heating / cooling of the filament.

Re: Keep blowing brake bulbs
I Had The Same Difficultly With My 2008 Crossfire Last Year. The Problem Was The Bulbs--- I Don't Remember The Specific Manufacturer But Bulbs Have A Great Tendency Of Blowing Out Prematurely. I Do Remember I Read The Answer Some Where On The Forum. I Got New Bulbs At Napa Autoparts ( Don't Remember The New Brand), But Have Had No Problemes Since. In Actuality,--- The Forum Had A Posting Which Gave Me All The Information For The Bulbs And Also Showed Me How To Replace The Bulbs In A Convertible Without Removing The Interior Portions Of The Trunk.

to make it pass and that is what I went by when I pulled it out. I'll buy new bulbs and try them
out. Hope that is all it is and man do I feel dumb right now. Thanks for all the help everyone.

Never never ever say that you feel dumb! Show me someone who never failed and I'll show you someone who never did anything or took any risks. Only by doing something and it not going right do we learn. I'll tell you a brief story about my first oil change. I got the oil, filter, tools to do the job. I put one can of engine flush in the oil cap, and ran it for 15 minutes like it said. I then took the drain plug off and changed the filter. I let it drain (drip, drip, drip) for about 15 minutes and wiped the drain plug and dipstick. I then opened each quart of oil one can at a time and put it in the oil fill on the valve cover. 5 quarts later I checked the level, and nothing registered. Yeppers, you guessed it, I forgot to put the oil plug back into the oil pan! Way back in 1973, oil was very cheap, but that lesson has stuck with me for almost 40 years. I (since then) recheck everything before adding any fluids twice! So its not being 'dumb', its just a learning curve. So come on in, tell us all these stories! Learn all about our cars, and save bundles of cash with the help you get here in this forum. In closing, I probably would have looked at the bulb number and got what was in it as well. Why would I doubt the bulb number that came out? Peace my friend!
