Additional Notes

The Hino FE2618 uses the P21W bulb for the back up light across the 1993-1995 model years.
The P21W is an ECE-standard single-filament signalling bulb rated at 12 volts and 21 watts, fitted with a BA15s bayonet base.
The BA15s bayonet base is a single-contact fitting, which is a key interchangeability factor. Bulbs with a BA15d double-contact base are not compatible, despite sharing a similar physical profile.
The ECE designation on the P21W indicates the bulb meets European and international regulatory standards, reflecting its origin as a globally adopted specification rather than a market-specific one.
At 21 watts, the P21W operates at a higher wattage than many smaller signalling bulbs, which is typical for reverse light applications where output intensity is a functional requirement.
