My wife has been telling me that one of the brake lights on our car is out, and asks me to fix it. So I go out to check it, and it seems to work fine! So I tell her that I fixed it. Then a few days later she tells me it is out again. Apparently someone she works with has been telling her that. So I go out to the car again and check it, and it works fine. Well, wouldn’t you know it, this morning I saw her driving the car down the driveway on her way shopping, and I saw that the brake light is not working. Very aggravating! So I guess it’s a short in the electrical system, which is going to be a pain in the neck to try to troubleshoot!
