. Click on philips, H4, Vision Plus 55 watt (correct wattage for your lights). Repositioned filament and xenon quenching/cooling gas makes this one of the very few 55 watt bulbs that really have increased light output on the road, with no heat or current damage to your lights, and no increased glare or scatter to oncoming drivers.
Otherwise, Sylvania, Osram, Wagner, or anybody elses H4 55 watt will work.
