If you look at your car, you will notice that sidelights have already been installed. These parker lights must be operational in order for the vehicle to be considered roadworthy in the eyes of the law. These are displayed when you are about to park your car on the side of the road. These lights are also commonly referred to as sidelights. Sidelights are designed to increase your vehicle's visibility to other road users, typically at dusk or in low-light areas such as tunnels or wooded areas. They're typically accessed through a switch that also controls the headlights.
When you turn on these lights, your number plate lamps turn on, making your car visible from a long distance. The majority of owners want to know when they should turn on the parker lights. If you are one of them, I must inform you that all vehicles must display LED parking lights for cars when parked on a road or in a lay-by on a road with a speed limit greater than 30mph. This makes parking on faster roads at night for extended periods of time impractical because leaving parking lights on for an extended period of time is likely to drain the car's battery.
Always keep in mind that driving a car without parking lights is illegal in Australia. If you are caught in such a situation, they may suspend your licence and seize your vehicle. You'll also have to pay a hefty fine.
