LED daytime running lights (DRL) are often custom-built in the latest cars with Xenon/HID headlights. But several recent cars use filament bulbs for DRL. These can be easily upgraded using replacement LED daytime running lights bulbs listed here. The DRL filament bulb types are: P13W (Audi, Chevrolet, Citroën, Mitsubishi, Nissan, Skoda), PS19W (Audi), P21W (Audi, Renault, Skoda, VW), W21W (Audi), PSX26W. Also dual intensity DRL and sidelight bulbs: P21/5W (Peugeot, VW), W21/5W (Vauxhall/Opel, Infiniti). H8 bulbs are used in some BMW models for 'Angel Eyes'. H8, HB4 LED bulbs can replace stock bulbs in foglights to be used as LED daytime running lights.
