Quick fit lighting.

There are a few different types of quickfit lighting available we use the radex type.

This is a quick and easy way to fit lighting and is available for some of our larger 5 and 6 function lights.

  • The lights come pre wired as shown.

  • On the back of the lights there are 2 sockets and studs to fix it to the trailer, as shown

The plug holes are 5 pin for the light operation and 4 pin to supply markers and number plate lights.

The cables consist of a standard seven pin plug into the towing vehicle. 2 Cables come out of the plug (1 for each light ). The cables terminate into plugs 1 red and one green which plug in to the back of the lights which are colour coded . These harnesses are available in 4m, 6m and 8m lengths Cables for side markers or number plate lights have a white plug to take power from the rear lights down 2 4m cables with female spade connectors.

Fitting quick fit lights is very easy, you do not even need to remove the lenses and is done by following these few instructions.

  1. Fix the light in place by drilling holes (2 for studs and larger holes for plugs)

  2. Bolt the light in place

  3. Plug the wiring loom in

  4. Fasten the wires in place this can be done with tiewraps or 'P' clips

  5. Plug in your car and off you go.

We do have sections in our shop for quickfit lights and cables.
