Sound and light alarms — general description (Mercedes-Benz E-Class W210)

Sound and light signaling on a car is designed to inform other road users of your intentions. For example, when changing direction, the driver uses the turn signals, when pressing the brake pedal, the driver behind is warned by the brake lights. When maneuvering in dense traffic, the high beam headlights are switched on. However, the driver of a Mercedes has even more signaling devices at his disposal.

Sound signal and hazard warning lights are mandatory equipment

According to the regulations for permitting vehicles to be used, each vehicle must be equipped with an audible signal. The hazard warning system is designed to enable the driver to warn other road users of a forced stop in an emergency. Since the hazard warning system must also work when the ignition is off, voltage is supplied to its switch directly from the battery through a fuse. The turn signals, on the contrary, receive voltage through the ignition switch only when the ignition is on. Signal devices must always be checked before driving.
