Additional Notes

The P21/5W is an ECE-standardized dual-filament bulb operating at 12 volts, with a 21-watt filament for braking or turn signals and a 5-watt filament for running or parking functions. It uses a BAY15d offset bayonet base, which physically prevents incorrect insertion by positioning its two base pins at different heights.
The Hyundai Veloster N uses the P21/5W bulb for its tail light function across the 2019-2020 model years, specifically in vehicles equipped with projector headlamps.
The projector headlamp condition attached to the P21/5W fitment indicates a trim or package dependency, meaning not all Veloster N units from those years necessarily share the same tail light bulb specification.
