i just recently got my disco, and on the bumper, there is a brush bar with two extra lights. they look awesome but i can’t figure out how to turn them on, is there a specific button? or is it something i have to wire myself?

 

Are you able to follow the wire? If there’s a wire into the cabin look for an aftermarket switch mounted somewhere. If nothing obvious then see if any of the cluster buttons like cruise control was wired for the lights. Some will grab a switch from the junkyard and add it to work for lights

 

If they're connected to the factory Fog Light switch you must have the headlights on for the fog lights to operate. Then if you switch to high beams the fogs will go out. You can reprogram the BCU to have them stay on with high beams with a nanocom
