Belysnings- og/eller signaleringsapparat til køretøj

The device (4) has a support (9) with a fixation screw for fixing the support to a vehicle, and a signaling element (12) for emitting light and used as a turn signal light, a stoplight, a side marker light, a fog light and a backup light. A mobile block (10) occupies a reference position relative to the support, where the block and the support are rigid. A helical spring brings the block in the reference position when the block is in an automatic return displacement zone and exerts plating force between the support and the block when the block is in the reference position. An independent claim is also included for a vehicle e.g. lorry and trailer, comprising an anti under-ride system.
