The Honda book list it as being "34901-GCH-004" which is a speciality bulb, however if your wanting to upgrade your lighting PIAA makes a performance replacement that uses less power to run it yet is noticably brighter and whiter (almots like HID's for an ATV) and those are known as the H6M or from some vendors will be found under the part number 20-0117. It looks kinda like a metal1157 base (like automotive brake lights use) with two connection points, but has a halogen bulb on the head.
H3 you can get one from your local auto parts store
low beam headlight bulb type: 9006
If you take out the bulb, it should have information printed directly on it. In my case (2001 Honda Civic LX 2 DR), the bulb reads 9003 HB2 H4 60/55W. If you get a 9003 compatible bulb, then it should work.
go to autozone and they will tell you exactly what type of light you need and you can buy your lihgt there it will cost around 8 or 10 bucks
