Acumen, the UK’s leading motorcycle electronics manufacturer, has introduced a device that is popular with riders in the USA because it helps reduce rear end collisions. It achieves this by drawing the attention of following traffic to the brake light more effectively than a normal brake light signal. Research by Mercedes-Benz engineers showed that the reaction times of following drivers are shortened by up to 0.2 seconds if a flashing red warning signal is used during emergency braking, instead of a conventional brake light. At 62mph this reduced the stopping distance of the vehicle behind by no less than 5.5 metres. Mercedes were so impressed that this technology will be standard on their new S-Class models in the future.
