Have a 2008 Jeep Patriot, headlights are starting to darken a bit when looking at the bulbs in the reflector, so I know it's time to replace. Philips Xtreme Vison seems to be the best choice from what I've read, although I also see a Philips Extreme Vision Plus. Going to purchase from a brick and mortar store, either one is available within a dollar per pair. Which is the better choice, or is there any difference other than packaging?
