Product Description

Part Number:

Most full-sized vehicles come with a 7-way round connection for trailer lighting. U-Haul trailers require a 4-way flat connection. With the Nite-Glow Adapter, easily connect any of our U-Haul trailers to your 7-way round vehicle outlet.

  • Simple Installation: No rewiring is necessary, so your installation is quick and easy.
  • Connect your trailer lights in the dark with no hassle! Not only is the adapter weather resistant and simple to use, but it also glows so you can use it during any hour of the day/night.
  • Functionality: Adapt a 7-round RV blade type vehicle outlet to a trailer 4-way flat.

Does this match standard UHaul trailer wiring?

–Michael Meier 11/6/2013 3:29:41 PM

Yes, it does. The Nite-Glow™ Adapter allows the 7-way round spade connector found on many light trucks and SUVs to easily connect to the 4-way flat plug found on all U-Haul Trailers and towing equipment as well as most single axle trailers on the road today.

Does this work for BMW? I am being told by a haul dealer that only a special 30$ 7 way works for BMW due to a little middle pin on the jazzy one that this adaptor doesn't have.

Our hitch pro writes: "When connecting an LED equipped trailer to an X5 factory installed 7-way trailer harness, you may experience a lamp out sensors, pulsing or flashing trailer lights and incorrect indicator flash speed. The U-Haul 39008 LED Light Trailer Module provides the necessary resistance for the BMW X5 to produce the intended functions when towing a trailer with LED lights."

If most full size vehicles come with a 7-way round connector, why doesn't U-haul make it's standard trailer connector work for most vehicles?

–Jim Burke 9/24/2015 6:34:31 AM

The 4-flat trailer wire harness is the most commonly used trailer plug and is industry standard for trailers that are not equipped with electric trailer brakes or other accessories (battery, light switches, reverse lights etc).

U-Haul offers the 47335 as a modest solution for vehicles already equipped with the 7-way connector only and needing to tow a trailer equipped with the 4-flat plug.

–Joseph 9/29/2015 2:10:44 PM

Will this also connect for the electric brakes on the 6' x 12' trailer?

–Scott 12/23/2016 2:57:47 PM

The 47335 will operate the trailer lights only. U-Haul 6' X 12' trailers are equipped with an automatic surge brake system.

–TIMOTHY 1/3/2017 2:33:48 PM

Is the adapter a rental or do we buy it?

–Alan 11/11/2017 1:38:26 PM

Hey, Alan! This product is currently only available for purchase, not for rent. Thanks for asking!
