EC-REVMF – Multi Frequency “White Noise” Reverse Alarm

Product code: EC-REVMF Category:


The rear blind spot can be a huge problem for all vehicles, with our Audible Reverse Alarms it can become a useful tool in order to alert traffic or/and pedestrians.

The Audible Reverse Alarm is an extremely useful addition to any vehicle including trucks, buses, vans, construction vehicles and Large Goods Vehicles (LGVs).

When a vehicle reverses, the device emits a loud external white noise which alerts anyone in proximity of the vehicle’s movements. The distinct “shh shh” of white noise is very different to tonal “beep beep” reverse alarms which means that it is easier to instantly locate where and what direction the sound is coming from. This helps avoids dangerous accidents and collisions.
