At first thought I reasoned... it must be a short... if it's BOTH lights they wouldn't have both burned out at once, right? I called our mechanic (who is exceptional and very honest) who recommended trying to replace the bulb first on my own before bringing it in to the shop. It would be easier and cheaper they said...
Off to the autoparts store. I walked in... baby on hip... and explained my problem. They looked up what kind of bulb our car required in the computer... and the grand total was $6.09! News to me that the turn signal and the brake light are the same bulb! I also got them to show me which screws to undo to get to the old bulb.
Later that day Baby Girl and I trekked out to the car (we live on a college campus and don't have parking close by). I sat her on a blanket in the back so she could watch me while I worked.
I must say... it was rather anticlimatic. Within a few mintues it was fixed! Just like that!
Jon was thrilled and I have so much more confidence now to try fixing things on my own that I previously may not have tackled.
