In the US, the sidemarkers are both turn signals and driving lights, hence they use dual filament bulbs. In the Euro spec, the corners are only turn signals and are single filament, which explains the bub base differences. The "city lights" are where the US amber/yellow fog lamps are located, but are clear. Explanations I've read indicated that the lights, which are power independent of the headlights, provide forward indication that the vehicle is a car and not a motorcycle if one of the main beams is not functioning. In the US, many motorist confuse a Euro spec equiped car as having its "high beams" on when they see all four forward facing lamps lit.
city lights are not located where the fog lights are.
they are located inside the headlight assembly itself. it is a 5 watt bulb,similar to a flashlight bulb.
u.s. drivers will sometimes think a person has their brights on because euro fog lights [on a benz] are white.
