There are lots of names for the bulb and manual lists it by type. You can do a search on the type (W?W), but if I remember correctly I found them to be a type 194. If you use LED instead of a real bulb, be sure to get them with LEDs on the sides as well as LEDs are directional and if you get one without side LEDs or other means to distribute the light it might not illuminate your side markers well.
