Position lights, also known as parking lights, are required on all motor vehicles when parked on a roadway or shoulder outside of urban areas. They are also required when a vehicle is parked on a roadway or shoulder within urban areas where the speed limit is more than 35 mph. These lights are used to make the parked vehicle more visible to other drivers, especially in low light conditions. **

Without more information, it is difficult to determine if the left parking light is defective. If the light is not turning on when the vehicle is parked, it may be a sign of a defective bulb or a wiring issue. It is recommended to check the bulb, fuse, and wiring to determine the cause of the issue. If these components are functioning properly, then it may be necessary to seek professional assistance to diagnose and repair the problem. **

Light does not travel infinitely far. While light can travel vast distances through space, it can be absorbed, scattered, or blocked by various materials and particles. The intensity of light decreases as it travels further from its source, eventually becoming too faint to detect. Additionally, the expansion of the universe can cause light from distant sources to become redshifted, making it undetectable with current technology. **

The parking light may come on instead of the fog light due to a few reasons. One possible reason is that the fog light switch may not be turned on, or there could be a problem with the fog light circuit. Another reason could be a malfunction in the fog light relay or a blown fuse. Additionally, some vehicles are designed to automatically turn on the parking lights when the fog lights are activated, so it's possible that the parking light is functioning as intended. **

Low beam is the standard headlight setting used for normal driving conditions, providing adequate illumination without blinding oncoming traffic. Parking lights are small, low-intensity lights located on the front and rear of the vehicle, used to make the vehicle more visible when parked. Rear fog lights are bright red lights located at the rear of the vehicle, used in foggy conditions to increase visibility to vehicles approaching from behind. High beam is the brightest setting for headlights, providing maximum illumination for driving in dark or rural areas with no oncoming traffic. **

The fog light comes on instead of the parking light because it is specifically designed to improve visibility in foggy conditions. Fog lights are positioned lower on the vehicle and emit a wide, low beam of light to help drivers see the road better in fog, rain, or snow. Parking lights, on the other hand, are typically used to make the vehicle more visible when parked or to indicate its presence on the road at night, but they do not provide the same level of illumination as fog lights. **

Yes, old light bulbs should not break during transportation as they contain hazardous materials such as mercury which can be harmful to the environment and human health if released. Proper packaging and handling procedures should be followed to ensure the safe transportation of old light bulbs to prevent breakage and potential contamination. Additionally, broken light bulbs can also pose a safety hazard due to sharp glass fragments. **

Light doesn't travel infinitely far because it can be absorbed or scattered by particles in the atmosphere or other mediums. As light travels through space, it can also be affected by gravitational forces and the expansion of the universe, which can cause it to lose energy and change direction. Additionally, the finite age of the universe means that light has only had a limited amount of time to travel since the Big Bang. Therefore, the distance light can travel is limited by these factors. **
