Flasher Units

Flasher Units

Smart turn signal control solutions for modern vehicles

Our Flasher Units (turn signal relays) switch a vehicle’s signal lights on and off in a rhytmic cycle. At nominal load, they operate reliably at a flashing rate of 60 to 120 cpm and detect the failure of a signal lamp, as required by the German Road Traffic Licensing Regulations (StVZO). 

They are suitable for vehicles with or without trailers, are designed for defined load ranges, and have been developed specifically for use in commercial vehicles and mobile machines.

On request, we can flexibly adapt standard Flasher Units to meet customer‑specific requirements.

Flasher Units product details

Load identification – The basis of every design

For the correct design of a flasher unit, it is important to determine the exact number of lamps on the towing vehicle and on all trailers at the start of the project. The calculation is always carried out per vehicle side.

Example

2 + 1 + 1 × 21 W (8 × 21 W)

  • 2 lamps on the vehicle
  • +1 lamp on the first trailer
  • +1 lamp on the second trailer
  • Lamp power: 21 W
  • Total load / hazard mode: 8 × 21 W

Additional lights, such as those mounted on mirrors or on the cab, must always be taken into account.
