Mercedes-Benz Metris Daytime Running Light Bulb Size

Additional Notes

• The Mercedes-Benz Metris uses the H15 bulb size for the daytime running light across all listed model years, spanning 2016-2023.
• The H15 is a dual-filament halogen bulb, meaning it contains two separate filaments within a single glass envelope, each serving a distinct lighting function.
• The H15 operates on a 12-volt electrical system, which is standard for passenger and light commercial vehicles, and carries a wattage rating of 55W for the high-power filament and 15W for the low-power filament.
• In the context of daytime running lights, the 15W filament of the H15 is the one typically active during daytime operation, while the 55W filament is associated with the main high-beam function.
• The H15 follows the ECE (Economic Commission for Europe) standard, a regulatory framework recognized across Europe and numerous other markets worldwide, governing bulb performance and safety requirements.
• The H15 uses a PGJ23t-1 base, a proprietary connector type that is not interchangeable with other common halogen bases such as H4 or H7, making direct substitution with those bulb types physically incompatible.
