Hi folks --- Three times during recent weeks I have been told that my left brake light was out on my 1971 Porsche 911T. At first I tried to bend the two contacts for the 1157 bulb and that did not work. I then tried using some dielectric grease, and that worked only until the car moved and then the light went out for good. So I looked at the internet and found a quick fix; namely, add some drops of solder to the two contacts and that should tighten the bulb up. I did that -- fixed the bulb in a box with a hole in it to make working on it easier, then placed some drops of solder on the two contacts. I added enough solder that the bulb did not want to lock in place! So I took a small file, and carefully took material off until the bulb locked to place. And guess what? The light now works like a charm!
