Ever since I read a little about them on Daniel Stern Lighting, and then tried them on my 2005 2500 with its pisspoor headlights, I started to use the Phillips Xtreme Vision bulbs on ALL my vehicles.
In short, they produce a noticeably brighter output that is still the yellowish/whitish color that I much prefer while not over drawing the oem headlight circuit.
IME, they ALSO last a LONG time which is something that cannot necesarilly be said for other higher output bulbs.
