The OSRAM ORIGINAL LINE S2 (64327) is a dual-filament halogen headlamp bulb designed for motorcycles and scooters equipped with BA20d bayonet-fit headlamps. Running at 12V with 35W per filament, the S2 delivers noticeably more light than the S1 variant — 650 lm on high beam and 465 lm on low beam — making it the appropriate choice for larger scooters and motorcycles where more illumination is required.

Manufactured to OSRAM ORIGINAL LINE standards, the 64327 is an OEM-grade replacement trusted by vehicle manufacturers worldwide, combining robust vibration-tolerant construction with a dependable, ECE-approved beam pattern.
