TEB4 Relay unit
This 4-way bypass relay may be used on negative earth vehicles that require a bypass relay to be fitted for circuit protection or to avoid confusing the bulb failure warning systems when towing a trailer or caravan. Do not use this relay on circuits which have modulated* outputs to the rear lamp clusters, as relay chatter, or incorrect or non functioning of trailer bulbs may result. Instead, fit the Universal 7 Way Bypass Relay TEB7AS.
Modulated outputs manifest themselves as low voltages, and often combine brake & tail or fog and tail lamps into one circuit.
