## Description

OSRAM LEDriving SL PY21W is an LED signal lamp for 12 V vehicles that replaces a PY21W lamp. It fits all conventional PY21W lamp sockets. The light is yellow, and compared with standard lamps it uses up to 80% less energy. OSRAM names signal and indicator lights as its main use. If you are replacing a red or orange signal lamp, choose a red or orange LED lamp.

This is an off-road lamp with no ECE type approval. You must not use it on public roads in any exterior lighting function: doing so voids the vehicle's operating licence and its insurance cover. The sale and use of these lamps is prohibited in several countries.

OSRAM gives a 4-year guarantee on LEDriving SL lamps.
