The LWL Relay Warning of Lights On is a device originally born as a warning light on, but over time it has found other applications such as the acoustic signal for door opening in buses, in signalling to the operator when the vehicle is not stable on the ground, risking overturning or when some lights remain on.

It is a simple and reliable acoustic device, all-in-one with built-in buzzer, both in continuous and intermittent mode.

The company in close contact with the customer is able to respond to specific needs by varying the software of the microprocessor on board the circuit so as to replicate the behaviour most useful to the needs of the installer.

These items have a metal bracket for fixing.
