DUAL-FILAMENT PRECISION WITH BIOLIGHT T20 WEDGE BULBS

The BIOLIGHT B-12V-21/5W-T20 WB-202 is a high-performance dual-filament replacement bulb designed for modern integrated stop and tail lamp systems. Featuring the popular T20 wedge profile, this bulb provides two distinct levels of brightness: a steady 5W glow for nighttime running lights and a sharp, high-intensity 21W burst when the brakes are applied.

Why choose BIOLIGHT B-12V-21/5W-T20?

Rear lighting is your primary communication tool on the road, and the WB-202 series ensures that communication is crystal clear. These bulbs are engineered to original equipment standards, offering an instant transition between filaments to alert other motorists immediately. The capless wedge design is particularly effective at resisting the corrosion and contact failure often seen with metal-based bulbs, while the reinforced internal structure is built to withstand the constant vibrations and thermal stress of daily driving.
