Additional Notes

The Mercedes-Benz Sprinter uses two distinct daytime running light bulb types across its model years: the H15 and the 7440, each built to a different regional standard.
The H15 follows the ECE standard, which governs lighting equipment across Europe and much of the world, while the 7440 follows the ANSI standard used in the United States and Canada.
The H15 is a dual-filament halogen bulb, meaning it contains two separate filaments within a single housing, operating at 55W on the high filament and 15W on the low filament, at 12 volts.
The 7440 is a single-filament wedge-style bulb in the T20 form factor, rated at 21W and 12 volts, with no secondary filament.
The H15 uses a PGJ23t-1 base, a pin-type connector specific to that bulb family, which is not interchangeable with the wedge-style base of the 7440.
On the Mercedes-Benz Sprinter, the H15 bulb applies to the 2019-2021 model years, but only on vehicles equipped with halogen headlamps.
The 7440 bulb applies to the 2010-2018 model years of the Sprinter for the daytime running light position.
Because the H15 and 7440 use physically incompatible bases and different filament configurations, they are not interchangeable with each other.
