A 7 way bypass is designed for vehicles which have Multi-plex wiring, Cambus systems or Bulb Failure devices which where introduced around the year 2000. This bypass prevents any faults on the towing vehicle's light system by switching power directly from the vehicle's battery/alternator to the trailer/caravan light system, using very small signals from the vehicle's light system, without the vehicles check control sensors system being adversily affected.
The 7 way bypass is fitted with a audible buzzer which will bleep every time the indicator flashes on the trailer/caravan when towing, if no bleep can be heard this means that the indicator on the vehicle has failed which results with the indicator on the trailer/caravan failing aswell.
