Your bulb will have an 'H' number - H4, H7, H11, etc - this may be printed on the headlamp glass. If you can get at the back of the headlamp, pull off the 3 wire connection plug, remove the rubber cover and the bulb will likely be held in place with a spring clip that you can squeeze to release it. Its best to take the bulb to a motor factors so that they can match it up for you. When you put it back it will only fit in its housing one way, so dont force it or touch the glass itself.
