Directions for typical Motorcycle LIGHT BAR Wiring

  Light Bar Lamps are mostly left on like your headlight.

  To ideally hook up a Light Bar, Locate one of the following:

Using a Relay is the preferable method:

For a finished look install some Light Visors (click here for instructions) and finish off the wiring with some available Chrome Cable Covering.

 Typical wiring shown using a relay.


Using a Relay: 

The switch or control power only needs to supply a small amount of current to trigger your relay (86).  Put a switch in series with the (86) trigger input to be able to turn the lights on and off.

Hook up heavier wire thru a fuse directly from the battery or Accessory Fuse Panel to the (in terminal) 30/51 and then to your lights.  You are now running all of your current through the relay contact instead of a switch which may not be able to handle the load, and possibly burn out.


Always use a relay or smart switch with the 45 watt or higher Halogen Lights. 




A Smart Switch, part number 05-777
 (Custom World) is an alternative and takes the place of a standard relay and switch

This is a sealed latching relay unit that can be installed anywhere, or in your headlight shell. 

This is a very easy way to use a sealed relay and  have switching all in one.
