Maypole 12 V 7 Way Bypass Relay With Audible Buzzer

The Maypole 12V 7 Way Bypass Relay with Audible Buzzer is designed for trailer and caravan towing electrics. It connects directly to your vehicle’s lighting circuits to manage lights on both trailers and caravans without adding extra load to the vehicle’s system. The built-in audible buzzer monitors trailer and caravan indicators and mutes during hazard warnings. This relay can be powered from the battery or fuse box and is compatible with vehicles using multiplexed wiring for position/brake and position/fog lights, provided these signals are physically present at the rear light clusters. Separate signal wires are required for indicators to function correctly, and the relay is incompatible with vehicles that rely on fully digital or network-based systems (like CANBUS) lacking direct wiring to the rear lights. Consultation with a qualified auto electrician is advised if you’re uncertain about your vehicle’s wiring configuration.
