The OSRAM ORIGINAL METAL BASE R10W is a reliable 10-watt halogen auxiliary lamp built to OEM quality, designed as a direct replacement for vehicles that use the R10W / BA15s fitting. Its unique half-silvered internal reflective coating creates a focused beam ideal for interior map lights, boot/trunk lights, and number plate illumination, where even illumination matters as much as brightness.

Backed by OSRAM's long heritage in automotive lighting, the sturdy metal bayonet base provides a solid, corrosion-resistant connection that stays secure over years of use.
