What is the reason when the position lights are not working but the headlights are on?

It may be due to a problem with the fuse or switch, and it needs to be repaired at a repair shop. Below are the relevant precautions for headlight maintenance: 1. First check if the lights are working properly during maintenance: When inspecting the lights, check if various types of lights (such as turn signals, taillights, fog lights, etc.) are functioning correctly. Additionally, check if the direction of the headlight beam is misaligned and if the brightness is sufficient. Regular inspection of the lights can help you stay informed about their condition and avoid accidents. 2. Replace bulbs regularly during headlight maintenance: Car light bulbs are consumables with a limited lifespan. Over time, bulbs will dim, reducing the illumination distance, which directly affects nighttime driving and poses a significant safety hazard. Therefore, once you notice dimming bulbs or a difference in brightness between two bulbs, replace them promptly to ensure driving safety. Moreover, avoid touching the bulbs directly with your hands during replacement to prevent contamination, which can shorten their lifespan. 3. Clean the headlights frequently during maintenance: Driving on roads after rain inevitably leads to splashing water, and mud spots may adhere to the headlight covers. Generally, headlight covers are made of special materials with excellent sealing. However, scattered mud spots on the covers not only affect the car's appearance but also impair the lighting effectiveness of the headlights.
I've encountered this issue before! Last time when driving at night, I found the parking lights weren't working but the headlights were fine, and I almost got pulled over by traffic police. After checking, I discovered it was a blown independent fuse for the parking lights, which isn't shared with the headlights. Some cars are designed this way. Additionally, parking light bulbs are particularly prone to failure, with a much shorter lifespan than headlights, due to constant vibration and their position making them susceptible to moisture. When I opened the lamp cover, I saw the bulb socket had oxidized and turned green, with the copper contacts corroded causing poor contact. Wiring issues are also common, especially the wiring harness near the rear wheels which can easily be eroded by mud and water. Remember, you can't just replace the bulb and call it a day - you must use a multimeter to check the voltage, otherwise you'll risk burning out the new bulb which would be even more troublesome.
