The OSRAM ORIGINAL GLASS WEDGE W5W is one of the most widely used automotive auxiliary lamps in the world. Found in side-marker lights, parking lights, instrument panel backlighting, number plate illumination, and courtesy lighting, the W5W's slim glass-wedge construction allows it to fit into the smallest of lamp housings where a standard bayonet-cap bulb simply won't fit.

This OSRAM ORIGINAL version is manufactured to OEM quality standards, ensuring a consistent 50 lm clear white output and dependable service life in every application — exactly what you'd expect from the world's leading automotive lighting brand.
