Intensify the style of your vehicle’s brake lights with the vivid red light of the OSRAM LEDriving SL Red.  

Why buy the OSRAM LEDriving SL LED P21W Red Rear Fog / Reverse Bulbs (Twin)?

Following on from the success of OSRAM’s LEDriving LED range of car bulbs, the LEDriving SL offers a similarly brilliant increase to lighting style and performance, in a brand new, stylish bulb design. The powerful red light that the LEDriving SL offers owes its intensity to OSRAM’s masterful design, which implements low-wattage, efficient LED technology.

Not only does OSRAM’s advanced LED technology ensure a striking, deep red projection, but its energy efficiency also allows for a huge bulb lifetime of up to 2500 hours – a massive increase compared to standard bulbs. This, alongside the LEDriving SL’s highly resilient, heat- and vibration-resistant construction, means that you can enjoy the bright red lighting upgrade for years to come.

On top of the styling improvements the OSRAM LEDriving SL offers, the heightened speed of the signal’s light offers a practical advantage to safety as vehicles behind you can infer and react to your intentions quicker. So you can drive comfortably, in confidence that your manoeuvres will be communicated to vehicles behind you as and when you make them.

As if that weren’t enough, the LEDriving SL comes with a generous four year OSRAM guarantee, and the bulbs’ simple plug-and-play design means you’ll be enjoying a vivid red light enhancement before you know it!

PLEASE NOTE: These LED car bulbs do not have ECE approval, and as such their usage is currently not approved for use on public roads: their usage is limited to ‘off-road’ applications. In addition, their installation may trigger a bulb error message to appear on the vehicle's on-board computer system / dashboard. This is a harmless side-effect and may be removed by installing a CANbus adapter.
