The reasons for the high temperature of the gear indicator light are: 1. The high temperature of the car engine and coolant reduces the cooling effect of the car's transmission; 2. The car's radiator grille is clogged. The solutions are: 1. Timely repair of the car engine's cooling function; 2. Prompt cleaning of the radiator. The gear indicator light is a tool that indicates the gear status. The driving speed is obtained by dividing the length of the road section by the driving time of the car, which can analyze the difficulty of driving and the traffic capacity of the road section. When driving, the car needs to select the appropriate gear according to the speed. If driving on a road without a centerline, the speed should not exceed 40 kilometers per hour, and when driving on urban roads, the speed should not exceed 30 kilometers per hour.

I've been driving for over twenty years and have encountered the issue of high temperature in the gear position indicator light several times. It's usually due to problems in the electrical system, such as a short circuit in the wiring or a blown fuse, causing excessive current and heat. Sometimes, it's caused by an aging bulb or poor contact, which becomes more noticeable during frequent gear shifts. If the transmission overheats, it can also cause the indicator light to heat up, especially in automatic cars during prolonged low-speed driving in traffic jams. It's recommended to first check the fuse box to see if the fuse corresponding to the gear position light is blown, and then feel the wiring to see if it's hot to the touch. Don't overlook this small issue, as it may indicate a larger fault, such as damage to the electrical system, which in severe cases can burn out other components or pose a danger. Regular maintenance should include cleaning the connectors to avoid dust accumulation.

As an enthusiast who often works on my own car, I believe that excessive heat from the gear indicator light is closely related to the transmission's condition. When the transmission fluid temperature is too high, the sensor may send false signals, causing the indicator light to overwork and generate heat. Additionally, if the bulb itself has reached the end of its lifespan or the socket is oxidized and loose, increased resistance can also lead to higher temperatures. Driving habits play a crucial role; for example, frequently flooring the accelerator on steep slopes or towing heavy loads can put excessive pressure on the transmission, leading to abnormal indicator light behavior. During inspections, first use a multimeter to check if the voltage is stable—if it's too high, there might be an issue with the alternator. Don’t wait until the light burns out to take action; regularly changing the transmission fluid can help prevent problems.

I commute to work by car, and the gear shift light often gets hot during traffic jams in summer. The reason could be simple, such as poor bulb quality or improper installation, leading to poor heat dissipation. Frequent gear shifting increases the circuit load, causing heat buildup. Environmental factors like hot weather or poor engine compartment ventilation also worsen the problem. It's recommended to check if the light cover feels hot after parking and, if necessary, try replacing the bulb. Keep the car's air conditioning running to help cool it down.
