Dual Filament T20/7443/580/W21W bulb also referred to as Polarg or M13 fitment too. These are intended to fit many cars and to be used in many applications, mainly for upgrading factory fitted halogen DRL (daytime running lights) from the standard halogen yellow to a more modern xenon white look.

You will find these used across many makes and models including Vauxhall cars such as the Insignia, Corsa, and Astra range.

Each bulb is 12V and is dual filament therefore runs at 21/5W depending on application. As these bulbs do not alter the wattage from factory bulbs they are fully CANBUS compliant and operate in exactly the same way as OEM bulbs. Fitment is easy, simply plug and play, remove old bulbs and fit these in their place, no modifications necessary.
