I want add-on driving lights for my '11 F250 to come on in conjunction with my high beams.

My highs add more light than the regular headlights, but doesn't throw much farther.

I think I want a pencil beam, but not too 'pencilly'. I often see trucks with 4 lights mounted, and am guessing the strategy is 2 floods and 2 pencils?

Also, Halogen or LED?

If you take the time it takes, it takes less time.
