Front position lamps
"Front position lamps",
[21] known as "parking lamps" or "parking lights" in the US, Canada
[10] and Australia and "
front sidelights" in the UK provide nighttime standing-vehicle conspicuity.
[25] They were designed to use little electricity, so they could be left on for periods of time while parked. Despite the UK term, these are not the same as the
side marker lights described below.
The front position lamps on any vehicle may emit white or amber light in the US, Canada, Mexico, Iceland, Japan, New Zealand and much of the Middle East; elsewhere in the world only motorcycles may have amber front position lamps; all other vehicles must have white ones.
[10][21][26][27] Colloquial
city light terminology for front position lamps
[28] derives from the practice, formerly adhered to in cities like Moscow, London and Paris, of driving at night in built-up areas using these low-
intensity lights rather than headlamps.
[29]
In Germany, the
StVZO (Road Traffic Licensing Regulations) calls for a different function also known as
parking lamps: With the vehicle's ignition switched off, the operator may activate a low-intensity light at the front (white) and rear (red) on either the left or the right side of the car. This function is used when parking in narrow unlit streets to provide parked-vehicle conspicuity to approaching drivers.
[30] This function, which is optional under UN and US regulations, is served passively and without power consumption in the United States by the mandatory side marker retroreflectors.
