Additional Notes

The Mercedes-Benz 250 uses the 17053 bulb for the map light across all listed model years, spanning 1968-1973.
The 17053 is a Wagner part number designation for a 12-volt halogen bulb intended for specialty automotive applications.
Halogen bulbs operate by cycling evaporated tungsten back onto the filament through a halogen gas reaction, which generally produces a brighter, whiter light than standard incandescent bulbs at comparable wattage.
The 12-volt rating of the 17053 is consistent with the standard electrical system voltage found in passenger vehicles of this era, making it a direct fit for the 250's map light circuit.
Because the 17053 carries a specialty application classification, substituting it with a general-purpose bulb of similar voltage may not produce correct fitment or light output for the map light housing.
