Purpose-fit bulb

The OSRAM 2845 W5W is a 24 V automotive signal lamp built for trucks and buses. It serves as a direct replacement for interior lighting, reading lights, instrument and switch illumination, plus position and parking lights. The glass wedge base matches factory fittings in commercial vehicles.

Deciding spec

Rated at 5 W and delivering 50 lumen, the bulb defines whether it matches the vehicle’s original equipment requirements. Verify that the application calls for a 5 W W5W source before fitting.

Thermals and draw

At 5 W the lamp draws minimal current from a 24 V system, keeping heat output low in normal operation. The compact wedge-base design runs quietly with no moving parts and places little load on the vehicle’s electrical circuit.

Questions about this item

What does the 50-lumen rating mean once the bulb is installed in a truck?

It provides a low-intensity white light suitable for interior reading lamps, instrument panels, switch illumination or position and parking lights.

How does the W5W wedge base limit the bulb's use in a 24V system?

The glass wedge base fits only sockets designed for the W5W standard, so it cannot be used in bayonet or screw-type holders even if the voltage matches.

What physical space does the 2845 bulb need to fit in a bus or truck lamp housing?

It requires a standard W5W wedge socket with enough depth for the glass envelope and base; no additional mounting hardware is needed.
