The Maypole 7-Way Bypass Relay is a crucial component for towing, designed to efficiently manage the lighting circuits of trailers and caravans. It connects directly to your vehicle's lighting system, ensuring that the trailer lights operate correctly without placing additional strain on the vehicle's electrical system. This relay features an integrated audible buzzer that actively monitors the trailer and caravan indicators, providing an alert for any malfunctions. The bypass relay can be powered conveniently from either the vehicle's battery or fuse box. It is compatible with most vehicle types and a wide range of trailer light combinations, including both filament bulb and LED lamps. The unit is capable of differentiating between dual voltage systems for tail/brake and tail/fog lights. Its flasher monitoring system uses an internal buzzer which automatically mutes during hazard warning conditions, and it also provides an ancillary output for panel lamps or additional buzzers. Designed for standard and modulated wiring, this Maypole relay helps to reduce test-pulse chatter and operates at 15A. Maypole is a leading UK supplier in the towing and touring sector.
