Re: rally car lighting

They're not the same light pattern as fog lights (well, not all of them). Some are "pencil" beams that reach far, some are closer to fog beams for close-in. Coverage is the name of the game.

They need them because the goal is to be driving as fast as possible, so you need as much light as you can get onto and down the road.

The reason they're on pods on the hood is because they're removable. They only put them on when needed, because they're very expensive and you don't want them getting damaged when not in use.
