I think you may be shocked at how much the regulations have changed since the old 50/55W maximum. Schedule 4 covers dip beam headlamps, and Schedule 5, main beam headlamps.
After a quick scan, all I saw was some minimum wattages (15W). Otherwise, they've to be white or yellow, turn on & off appropriately, point in the right direction and be mounted in the right place.
