VIN DecoderDecode your S2000's VINThe tail illumination bulbs in the AP1 rear lamps, separate from the 7443 tail and brake bulb. Each 2000 to 2003 tail lamp assembly carries one 12V 5W T10 wedge, Honda part 34351-657-921, so the rear of the car still shows light if a 7443 filament fails.
Same wedge family as the other 5W positions on the car, so 168 and 2825 interchange here. Straightforward LED swap with no hyperflash concern since this circuit does not flash.
There is no AP2 equivalent: from 2004 the tail illumination is LED inside the sealed lamp unit, covered by the AP2 tail and brake entry.
