If you're looking at the bumper on the XJ, that's an ARB. Photobucket is having issues or I'd post pics of my ZJ bumper he built. He has only does local work, fits them up on the vehicle, then removes to finish weld.
Decided new marker and parking lights were needed. Also found matching black pieces that the marker lights fasten to. Not bad, about $65 shipped, all are new.
First click on the switch is parking lights. Headlights should not be on.
Dimmer switch is on the left side of the column. Pull it towards the wheel to switch between high and low beam.
Turn signals could be bad ground, bad flasher, or bad switch. My money is on the ground.
