A clear message for every mission.

The roof bar.

Customers can specify any version of the new Hella RTK-7 roof bar on any BMW Authority Vehicle (subject to compatibility with the other equipment specifi ed). The RTK-7 is even more aerodynamic than its predecessor, and incorporates high-intensity energy-effi cient LED technology. On the BMW 3 Series Touring, the RTK-7 can now be attached directly to the roof rails. The optional signalling device is based on an LED matrix, and can be programmed with any message, whenever required.
