I have been wanting some lights for my XJ and saw these at the Harbor Freight store for $24.
Off-Road Long-Range Truck Light System

I decided I would test them on my Sheriffs Ride (since Im out in that truck more often).
I installed them in about an hour. The kit comes everything you need (wiring,switch, fuses (already mounted in the wire))...its basically idiot proof.
All I had to do was splice in some longer wires since my siren box/control was located under the back seat.

I mounted mine on the my grill guard and might spring for two more if I like them.

Depending on how they do, Ill probably spring for more for my XJ and Sheriffs Ride. I like the fact that they cost $24 vs $60+ for the PIAA, KC, ARB lights.
