Full-voltage vs. parking light headlamp on European-market Volkswagen, 2007. Depending on prevailing regulations and equipment, vehicles may implement the daytime-running light function by functionally turning on specific lamps, by operating low-beam headlamps or fog lamps at full or reduced intensity, by operating high-beam headlamps at reduced intensity, or by steady-burning operation of the ...
The emergency stop signal is automatically activated if the vehicle speed is greater than 50 km/h (31 mph) and the emergency braking logic defined by regulation No. 13 (heavy vehicles), 13H (light vehicles), or 78 (motorcycles) is activated; the ESS may be displayed when a light vehicle's deceleration is greater than 6 m/s 2 (20 ft/s 2) or a ...
Tail and brake lights are red and emit light to the rear so as to reveal the vehicle's direction of travel to following drivers. White rear-facing reversing lamps ...
Anti-lock brakes enable ESC to slow down individual wheels. Many ESC systems also incorporate a traction control system (TCS or ASR), which senses drive-wheel slip under acceleration and individually brakes the slipping wheel or wheels and/or reduces excess engine power until control is regained.
The warning is followed by light braking to get the driver's attention. The third phase initiates autonomous partial braking at a rate of 3 m/s 2 (9.8 ft/s 2). The fourth phase increases braking to 5 m/s 2 (16.4 ft/s 2) followed by automatic full braking power, roughly half a second before projected impact. "Pre sense rear", is designed to ...
The sensor has an input port to measure the hydraulic braking pressure and an electrical connector output for a wire connection for feeding the warning light. Some brake failures do not trip the sensor into a fault mode. A brake fluid pressure sensor is used in anti-lock braking system (ABS). ABS fault lights come on with unexpected wheel lock ...

Head end power (for passenger versions) is taken from the intermediate DC link; the DC power system which is also used for dynamic braking. [11] [9] The braking systems typically used are a combination of rheostatic and disc brakes. [9] The first EuroLight was unveiled at the InnoTrans trade fair in Berlin in 2010. [12]
