Start your adventure early.™

– No cutting wires in the back of your vehicle, trying to attach lots of brake, turn and tail light wires to just 4 trailer wires.
– Uses 12-volt power from your vehicle so runs indefinitely with no batteries.
– Transmission range: 280 feet / 85 meters.
– North American development, support and shipping. We made these to use with our own boat trailers. This also means no import fees, and fast delivery.
– 2-year warranty and easy returns.
– In-vehicle LED warning light if transmissions are not being received.

We are not aware of any other product that provides wireless sensors in the vehicle. Unlike most towing lights claiming to be wireless, these do not require that you have a trailer connector wired in to your vehicle’s tail lights. We use Inertial Motion Unit (IMU) sensors in the vehicle — the same digital gyroscope and accelerometer used for orientation in fighter jets and in the SailTimer Wind Instrument. No trailer connector required.

Other versions: Vehicle-Trailer Set, Trailer Kit. Accesories: 4-pin to 7-pin adapter. Amber Side Marker Lights.
