Havent posted here in a good long time!

Still got my Jeep, added a few things to it (new sound bar, top and MP3 Player connector)

Im looking at getting new lights for it now. Headlights and foglights.

Few questions though..

Whats the difference between a foglight and a driving light? I assume the driving light is on ALL the time? What are the benefits from getting a driving light and fog light system as compared to just a fog light system?

Will my stock battery be able to run fog, driving, and new headlights?

Thanks!
