Is it easy to catch fire if the lights are left on all the time?

It is not easy to catch fire if the lights are left on all the time, but keeping the lights on for a long time will cause the vehicle battery to lose power. The lights refer to the lamps on the vehicle, which are tools for road lighting and signaling various vehicle movements during nighttime driving. Composition of vehicle lights: 1. Position lights: used to alert other road participants; 2. Turn signals: signals given when the vehicle is turning to alert others; 3. Headlights: composed of low beam and high beam for illumination; 4. Fog lights: light signals used in foggy weather; 5. Reverse lights: to alert pedestrians and vehicles behind; 6. Brake lights: to alert following vehicles.
I always found it quite scary to leave the lights on constantly, and as an ordinary car owner, I used to be particularly afraid of them catching fire. However, from various forums and friends' experiences, as long as the lights are designed properly, the risk of fire is very low. Modern cars have fuse protection systems that automatically cut off the power when the current is too high. Although headlights like halogen ones can reach temperatures of up to 100 degrees Celsius after prolonged use, their heat dissipation structures prevent overheating. A neighbor once forgot to turn off the interior light for two days—the battery died, but the light itself was fine. The real danger lies in improper modifications or aging wiring: for example, installing additional exterior lights without properly handling the wiring, leading to insulation damage that causes short circuits and sparks. I make it a habit to check and turn off the lights before parking, which saves power and gives peace of mind. New cars use LEDs, which generate even less heat, so there's no need to worry too much. The key is to maintain the factory settings and avoid tampering with the electrical system. In short, the probability of a fire is extremely low, but it doesn't hurt to be cautious.
