Mercedes-Benz Brake Lights
Friday, June 29th, 2007The Mercedes-Benz brake lights was first introduced in 2005 in Germany. It was approved by the European Union licensing authority to enter production in the S-Class and later in the CL-Class coupe. Mercedes-Benz developed this technology to improve driver awareness and reduce rear-ender accidents.
Research by Mercedes-Benz engineers has shown that driver reaction times are shortened by up to 0.2 second if a flashing red warning signal is given instead of the conventional non-flashing brake light during emergency braking. The studies carried out by the team at Mercedes found that at a speed of 50 mph this reduces the stopping distance by approximately 14.5 feet, and at 62.5 mph by around 18 feet.
Specialists at Mercedes tested various warning light systems during their study. Brake lights which light up four times as quickly as the amber hazard warning flashers during emergency braking proved particularly effective in alerting following drivers to the danger of a rear-end collision. The Mercedes study also revealed that switching on the hazard warning system in a dangerous situation has no significant effect on the reaction times of other drivers.
However, the National Highway Traffic Safety Administration (NHTSA) rejected Mercedes-Benz’ proposal to equip its vehicles with brake lights that would rapidly flash on and off when a driver brakes suddenly, despite the fact that NHTSA’s European counterpart has endorsed the system.
But the agency replied that Mercedes had not proved that flashing lights would yield a major safety gain, so existing federal rules that require steady illumination of brake lights will stand.
Mercedes-Benz USA LLC is still persisting in its campaign to bring flashing brake lights to the United States. The company is counting on its customers to help convince U.S. regulators of the safety benefits of brake lights that flash rapidly in emergency stops. Mercedes-Benz has asked the National Highway Traffic Safety Administration for a two-year exemption from federal rules that require “steady-burning” lights on vehicles. The company said that in those two years, it would sell as many as 5,000 cars with brake lights that flash during panic stops. The experiences of the cars’ owners would help determine the value of the flashing lights. Those drivers would be rear-ended less often and less severely, Mercedes-Benz predicts.
