The Supervisor is a LED warning light bar for emergency vehicles. Besides a high visibility it offers a clear communication with other road users. To achieve this, two additional lights have been integrated into the front and the back of the light bar. These multi-colour LEDs are connected to the vehicle and serve as daytime running lights, interval and brake lights. The Supervisor also provides all necessary warning configurations as well as a searchlight function. Size and light configuration of the bar which has an elegant form, tapering to the side, are freely selectable.
