Complies to EU regulations



whipflash based on the most effective way to increase road safety by using a flashing brake light. Flashing brake is considered the best method of drawing attention to the present users of panic braking and danger.

The technology to detect the movement of the vehicle based on a twin-axle sensors which are integrated in a circuit. Measure the values calculated then mathematically to next activate appropriate signals to the present road.

WF II series is built into a standard relay box for easy way to fit both in the automotive spare relay sockets and be attached with the supplied bracket.

WF II connects only to the supply voltage, which varies depending on WF II model. Thereafter, only the signal from the brake pedal and outgoing signal to the brake light that is connected. This is done through a few changes at brake pedal switch to detect when the brake pedal is pressed down. If you want to use the governance of the warning indicator connected another cable that in most cases in modern vehicles only connects directly to a pipeline at the warning blinker switch in the vehicle.

When the emergency brake light must show red light and the usual stop, it can be as appropriate use of fog light on the vehicle. Connection is then in the same way, but instead connected WF II immediately after the fog lamp switch.
The advantage of using fog light is emergency braking seen better.

Model-specific data

WF II-H is a standard model developed to fit the vehicles of weight classes over 3500Kg. Deceleration host are designed for trucks, heavy trucks and mobile homes. WF II-H is a standalone product that requires no external sensors or signals, but connected only to the supply voltage and signal lines for the brake or the like, and warning indicator if desired.

Detection by the twin-axle sensor is used to:

  • Collision detection: front, side, rear
  • Hard and panic braking
  • Automatic activation / inactivation of warning indicators
  • Sudden tilt (Trench Running example)


WF II is slightly more complicated than in WF to install as it needs
mounted in a relay base, with the supplied bracket in the appropriate place.
WF II must be mounted standing straight up in order not to risk errors in motion sensing. In addition, any of the pages in line with the vehicle, therefore, may not
WF II rotated diagonally.

Then connect the desired lines and voltage is switched back on. If the brake light illuminates normally have the installation is successful. Then run the vehicle up to about 50km/h which then a panic braking is done. WF II is then installed.
