Teams at Silverstone are currently testing a new brake light system, wired into the high intensity light that is mandatory on all F1 cars. Introduced at the suggestion of Ferrari technical Director Ross Brawn in light of consecutive accidents to Michael Schumacher and recently championed by the Williams BMW team following a sequence of 'rare' rear endings. The new system is designed as an early warning to following drivers, felt to be particullarly important if the leading car brakes unexpecdedly. Not all drivers are in favour - Jordan tester Ricardo Zonta is quoted as saying "It could help, but you don’t really have any time anyway. If you are behind someone and the guy touches the brakes, and you touch them later, then you’re going to hit them already, because the brakes are too good."
In a related move the FIA are keen for teams to adopt an 'indicator light' system - a concept not as strange as it sounds. A source close to Max Mosley is quoted as saying "The new brake lights will warn a following driver of a sudden loss of speed, but following traffic has no way of knowing if a driver is about to move sharply in a particular direction - to avoid some debris, or to overtake for example. The system is an important passive safety measure". It seems that the lights would be activated automatically if a certain degree of steering lock is applied, but would only show at the rear of the car to prevent warning the driver ahead of an overtaking bid.
