The Light Ranger MUTT allows one-man testing on lights and electric brakes found on most light-duty trailers without needing the tow vehicle. Designed for 7-spade, 6-round and 4/5 pin configurations, it tests trailer connection to taillights, turn signals, backup lights, electric brakes and grounds. Less expensive than a citation for improperly working trailer lights, the Light Ranger MUTT checks all critical areas of electrical function prior to use. The Light Ranger MUTT is water-resistant and capable of withstanding harsh conditions. It includes a battery charger and three-way adapter.
