Well, I will wait for others to reply for type of bulb (me thinks it's H7 but not sure). For brighter bulbs, there are, Philips Racing vision (poor lifespan though), Philips Xtreme Vision / White Vision. Osram Nightbreaker (various inc, Laser, Unlimited), and also Bosch's Pure Light / Gigalight+120s or Ring Xenon 130...just for a few to get you started. Most of these (if not all) would give you a whiter light beam, and all for sure will give you a brighter beam. Life expectancy...well most should see you over a year if you use your car in the dark everday (eg...returning from work).
