How Good Is Your Rainlight?
If your answer is "if it passes scrutineering, good enough" then perhaps I may ask you to reconsider?
When I was sorting out the pictures for the Castle Combe reports, I didn't include this one, but I thought it might be worth a view as a separate item. There are 3 cars in the picture and I believe that all 3 had good quality, effective rainlights. Looking at the grid from the same angle when there wasn't any spray, some of the rain lights seemed a bit weak to me. As I seem to have parked myself up on the competitors' scrapheap, I'm probably ill qualified to comment, but it did occur to me that if I ever took up competing again I would make sure that I had the best rain light I could afford. After all, if a slow moving car with a poor rain light had been travelling between the first and second of these 3 cars, would it be visible? And what if there were 5, 7,10 cars in the picture?
PostScript: Between writing this and posting it, I received the Formula Junior Historic Racing Association magazine. It contained the following plea on the editorial pages from their technical man Grant Wilson and is repeated with thanks: "A good FIA approved square type rain light is far better than the smaller round units. If changing yours consider other competitors' view of the rear of your car."
