I'm not clear as to the type of light you want. Fog or driving or both. For twisty, narrow trails a powerful fog mounted at bumper height would help. For more open roads, a light with driving beam would be usefull.
Some of the better brands include PIAA, Catz, IPF and Hella. The model that looks on your X is a matter of your preference. Usually the kits come with a full wiring harness including fuse, relay, switch and indicator light. You can set up the circuit so the lights will come on whenever you choose. For example, I replaced the OEM fogs and have them set so they can be used whenever the parking lights or hi/low beams are on. OTOH, the IPF 960 driving lights can only be selected if the hi beams are on. Just depends where you connect the relay's signal wire.
