Many of today's vehicles do not possess the electrical means for powering the extra voltage requirements of a trailer. Power Taillight Converters units completely isolate the tow vehicle from trailer malfunctions. Power is taken directly from the battery for isolation and brighter trailer tail lights. The Short-Proof Power Taillight Converter is also a self-resetting power converter that will reset after the short has been fixed in the trailer wiring, providing extra protection for the vehicle wiring.
