Will the car catch fire if the lights are left on for a month?

Leaving the lights on continuously is unlikely to cause a fire, but it can easily lead to battery depletion. The battery capacity in cars is not very large, and prolonged use of the lights will drain the battery, potentially causing it to lose power and affecting the normal operation of the vehicle. Here are some proper methods to maintain your car battery: Regular cleaning: During daily use, pay attention to the condition of the battery. Over time, the battery may become covered with dust, powder, oil, etc. To ensure proper functioning, clean the battery panel and terminals regularly to extend its lifespan. Avoid long-term parking: If the vehicle is left unused for an extended period, the battery will self-discharge. Therefore, even if you don't use the car often, it's recommended to start it once a week and take it for a short drive to keep the battery fully charged. Regular inspection: The typical lifespan of a car battery is 3-4 years. For high-end models with more electronic systems, the battery life may be shorter. Regular checks of the battery's charge level can help maintain it in optimal working condition.
I've got experience with this. The chances of a fire from leaving the lights on for a month are really slim. Most car lights are cold light sources, like LEDs, which generate minimal heat—temperatures max out at around 40-50°C, nowhere near ignition levels. The real issue is the battery. A car battery discharging for extended periods can suffer severe depletion, and deep discharging may cause it to overheat. If the wiring is old and short-circuits, there’s a slight fire risk, but most cars have fuses that will blow in time to prevent disaster. My old car once had its lights left on for three days—the battery died, costing me 500 bucks to replace, but no fire. My advice: check your wiring regularly and don’t take the risk. It saves both power and money.
