Yep, get the Philips Xtreme Power 9007s.
Candlepower has them, among other vendors. They are the best 9007s currently available. Make sure the headlamps are in good condition; if the lenses are at all clouded or fogged,
polish and recoat them. And make sure they're
aimed carefully and correctly.
The suggestion to put in
relays and better wiring is good advice; Ford's headlamp wiring tends to be far too thin for efficient power supply to the bulbs.
The suggestion to use bulbs with a higher-than-stock-wattage filament is bad advice for numerous reasons; the nutshell version is that it will cause more problems than it solves.
Ford does not list export headlamps in their North American parts catalogues. It looks as though that body style of Explorer might have been sold with a European-compliance package (see
this ad) but you would have to go to great effort and expense to get them, and they would likely not be better. Different, but not better -- Ford's North American operation, like GM's and Chrysler's, have long tended to cheap out on their European-market compliance equipment. There's an attitude in the US industry that the rest of the world should just adopt US standards (in reality the reverse is the case, the US should adopt the rest-of-world European standards). But most of the export-spec headlights for US-model Ford vehicles are bare-minimum in performance and construction quality...probably not worth bothering with.
