For the 2002 Honda S2000, the low-beam headlight uses a D2S bulb, while the high beam uses H1. The daytime running light also uses an H1 bulb. The supplied fitment data does not list a headlight-type variation, so these applications should be checked against the vehicle’s existing headlamp assembly before ordering.
Other notable exterior bulbs include 7440 for the front turn signal and reverse light, 7443R for the brake and tail lights, and 7507 for the rear turn signal. Both front and rear side markers use amber-tinted 168NA bulbs. Parking and trunk lighting may use either 168 or 917, while the license plate application may use 2825 or 98. The center stop light is listed as an integrated LED assembly, and the map light uses DE3022.
