A system is described for controlling an electrical supply to auxiliary equipment such as a tail lift (10) attached to or within a vehicle. The system comprises means for supplying power to the auxiliary equipment when the vehicle's hazard warning lights (11, 12) are switched on. A latching device (15) is also included which is operable to maintain the power supply to the tail lift (10) when the hazard warning lights (11, 12) are subsequently switched off. Switching means (16, 17) are provided which are operable independently of the hazard warning lights (11, 12) to cut off the power supply to the tail lift (10). Thus, the system provides that the tail lift (10) is energised when the vehicle's hazard warning lights (11, 12) are switched on. It gives the vehicle's driver the capability to have the hazard warning lights (11, 12) operating throughout the time that the tail lift (10) is energised. Alternatively, the hazard warning lights (11, 12) can be switched off whilst leaving the tail lift (10) energised. In yet another alternative mode, the hazard warning lights (11, 12) can remain in operation whilst the tail lift (10) is switched off. |
