... I had Silver Stars in my low beams for about the last 10,000 miles. They both burned out simultaneously. What is the chances of that happening again?
Actually pretty good... since that quirk is not uncommon!

My left headlamp went out and I went to an auto parts store to buy a replacement. Went home to change the bulb and noticed the right one was out also. Had to go back the same day and buy another bulb! :roll:

Others have had both lamps go out at the same time, too.

When I bought my '01 in June, the former owner told me to change the headlight bulb immediately after it burns out; he said the other bulb will usually burn out within 30 minutes if you don't. It has something to do with the load placed on the system- amp draw/voltage when the bulb burns out, it really changes light system amp/volt readings. ....
IF a single wire supplies both bulbs, then I think it might be the voltage drop across that wire that causes this effect. When one bulb goes out then the voltage drop across that wire is suddenly less and the remaining bulb begins to get a slightly higher voltage. On an aging bulb that's probably enough of a change to finish it off.

It's probably a 'best practice' to go ahead and change both low beams when one goes out.

Just guessing, but that's my story and I'm stickin' to it!
