9003, Maybe

The bulb # is 9003. I put Sylvania 9003 CB in the CR-V. The headlights seemed to be aimed just fine after changing bulbs, but your experience may be different if the bulbs have the filament located differently from the ones you are replacing.

The light is indeed slightly bluer, but I only noticed this because I tested them with one bulb changed. But it's not really worth extra money ($15 each) unless you like to keep the originals as spares. I think you can get standard halogens for $9 each.
