Full-voltage vs. parking light headlamp on European-market Volkswagen, 2007. Depending on prevailing regulations and equipment, vehicles may implement the daytime-running light function by functionally turning on specific lamps, by operating low-beam headlamps or fog lamps at full or reduced intensity, by operating high-beam headlamps at reduced intensity, or by steady-burning operation of the ...

What most of these converters do is to bring together the turn signals and stop lamp signal from a three-wire solution using 54, L and R into a two-wire solution using L54 and R54 according to DIN where brake light and turn indicator uses the same wire and bulb for each side. These converters usually don't handle the case of separate position ...
In 1986, the central 3rd brake light was mandated in North America with most of the world following with similar standards in automotive lighting. [54] Airbags were first installed in production vehicles in the 1980s as standard equipment instead of an option as was done in the mid-1970s (such as the Oldsmobile Toronado in 1974 [50] [55] [56]).
