Now a standard fitting in Europe and being adopted by many other countries, daylight or daytime running lights (DRL's) are those bright white lights seen on many new cars. How can you miss them as they drive towards you ?

They are designed so that other drivers see your vehicle, even in bright sunlight. Daytime running lights turn on automatically when you start your engine and automatically turn off when you turn your headlights on (a NZ Transport and warrant of fitness requirement - R48). R87 compliant.
