Leader lights
LED position panels on the bodywork showing whether a car runs first, second or third in class.
Leader lights are the small LED panels on each car's flanks that broadcast its live class position: the panels illuminate to mark the cars running first, second and third in their class, so spectators and rival crews can read the podium order at a glance.
They exist because multi-class racing scrambles the visual order: the car physically leading on the road may be running fourth in class three laps down. The lights, along with class-coloured number panels, are how endurance racing makes four simultaneous races legible from the grandstand.
