When the Mercedes W05 was unveiled to photographers, the rollhoop shone with the light from an array of green LEDs.
Rather than this being a reflection of the fuel sponsor's colour scheme, it was the first view we've had of a new safety-light system for 2014's more powerful ERS.
Up until last year, any car fitted with KERS had to have a safety light on top of the chassis to warn marshals and mechanics of the car's electrical safety status.
