Testers Manual item No 27 : Horn
Vehicles used from 1st August 1973 must have a horn that produces a continuous or uniform sound. If the horn does not work it is a reason for MoT test failure.
Testers Manual item No 34 : Pressure / Vacuum Warning.
Vehicles used from 1 April 1983 can be fitted with either a visual or audible warning device to indicate low air brake pressure.
Fitting an audible reverse warning bleeper will help to reduce risk by increasing the awareness of vehicle movement to passers by , pedestrians and staff working in the vicinity of the vehicle.
The reverse warning bleeper can be installed to activate when reverse gear is engaged either by direct wiring to the reverse gearbox light switch or to reversing lights circuit where circuit rating is sufficient to carry extra load, or triggered via a relay and its own power circuit.
Some reverse alarms have a "Night Silent" facility where an extra wire is fitted to the sidelights circuit to sense when lights are on and deactivate the alarm to avoid nuisance in built up areas.
Consider installation of warning beacons, reflective strip, work lamps and extra visual aids for the vehicle driver including cctv monitoring equipment and extra mirrors.
