For the 2005 Honda S2000, the low-beam headlights use D2S bulbs, while the high beams use H1 bulbs. The daytime running lights also use H1, so confirm the lighting position before ordering replacements.
Other exterior fitment highlights include 7440 bulbs for the front and rear turn signals and reverse lights. The parking lights and front side markers use 2827 bulbs. The brake lights, center stop light, tail lights, and rear side markers are listed as LED applications rather than replaceable bulb sizes.
- License plate lighting: 2825 or 98
- Map light: DE3022
- Trunk light: 168 or 917
No fog-light bulb is listed for this fitment. Because the supplied data does not identify alternate headlight configurations, use the D2S low-beam and H1 high-beam specifications for this model-year listing, and verify the original bulb before purchase where multiple options are shown.
