Feel free to add your own upgraded bulbs for the S3 (ideally with links and photo’s showing before and after)   Front Fog lights    H8 35W (OE are Osram)   I upgraded mine to 4,500K ( K = Kelvin colour temperature, OE Xenon’s headlights are between 4,300K - 4,500K)   4,500K halogen on left OE std halogen on right:     A much better colour and very close to the DRL’s, however they were pretty crap with regards to the light they emit
