## Description

OSRAM LEDriving SL WY21W is an LED retrofit lamp for signal lights: it replaces a WY21W lamp and fits all conventional WY21W lamp bases. It is mainly used in signal and indicator lights, gives a yellow light and uses up to 80% less energy than standard lamps.

If you replace red or amber signal lamps, or lamps that sit behind red or amber lenses, choose red or amber LED lamps to match.

The lamp has no ECE approval and is for off-road use only. You must not use it on public roads in any exterior lighting function: doing so cancels the vehicle's operating licence and its insurance cover. Several countries ban the sale and use of these products.

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