Well like a lot of British car owners I am using the cold weather to fix some things. I finished my restoration in May and put about 1600 miles on it. One disturbing issue that has shown up twice is at night when the headlights will turn off while driving. Both times I was slightly curving (turning) going down the road. This isn't as fun or exciting as you might think it would be and it is worse when the wife is with you (both times). I might mention that I have not driven it alot at night so the two times is way too much to ignore. So my first thought is the wires are pulling in the steering column maybe at the headlight switch. The wires (TR4A) are very tight in there. I can't remember but I think they are up against the steering rod and could be pulled by it when turning. Before I start on this I wanted to see what others have experienced and what they did about it. By the way I have LED lights. Am I looking in the right place and what is the fix? Bruce
