Depends on the truck grille. But you can never go wrong with bigger heads.

Go with a headlight flasher for forward facing white light and do solid blue M4s. I spec'd PD Tahoes with solid M7s and even with the high beams flashing they don't get drown out, presents a nice large footprint from a distance.
