Get any brand-name E-code housing - IPF, Hella, Autopal, Bosch, etc.. then, decide if you also want to upgrade your wiring harness with relays to support higher-wattage bulbs. If so, IPF Fatboys are indeed awesome - I have them (in IPF housings with an IPF harness) and they're great. If not, Osram Silverstars or Nightbreakers are well regarded as 55 watt bulbs. If you go beyond 55 watts without upgrading your harness, you risk burning out your headlight switch. Even with 55 watt bulbs, you will more power to the headlights with a relay kit. Either way, it's a truly plug and play installation that is well worth it compared to the stock sealed beams.
