Short: Why do certain race cars have yellow headlights



In some forms of GT racing in the US, multiple classes run together in the same race. The yellow headlights allow drivers to see whether a car behind them is in the same class as they are. Because the yellow headlights are usually in the slower class, it's usually a matter of a driver in the slower class seeing WHITE headlights in his mirrors and being able to tell the car behind him is in a faster class. In short, it's a way for drivers to tell whether or not the car in their mirrors is one they're actually racing for position with.
