I've been driving our old 96 Bronco a lot lately. It has the factpry headlights with halogen bulbs that have been replaced a couple of times with ordinary halogens (not silverstar, etc..).
I have no problem driving the Bronco at night compared to the 2011 mustang or even our 2012 F150 with factory halogens. The newer reflectors just dont work as well as the ones in the Bronco.
