Uncle Wang is a retired senior who is enthusiastic about outdoor activities. In his leisure time, he always enjoys driving his electric four-wheeler, taking his wife along for outings everywhere, and savoring the comfort of life. This electric four-wheeler is like their “mobile small home”, accompanying them through many wonderful journeys.

One evening, Uncle Wang, as usual, was driving his wife to the countryside to watch the sunset. When they were driving on a narrow rural road, suddenly a rapid honking sound came from behind. Uncle Wang was puzzled. He had been driving normally, so why was someone honking continuously? He looked through the rearview mirror and noticed that the vehicle behind was constantly flashing its high beams, seemingly signaling something to him. Uncle Wang quickly pulled over and got out of the car to check the situation.

To his surprise, he found that the rear taillight of his electric four-wheeler was not working. In the gradually darkening evening, driving without a rear taillight was extremely dangerous. It not only made it difficult for the vehicles behind to judge the distance but also might lead to rear-end collisions. Uncle Wang and his wife looked at each other, realizing that they had to solve this problem as soon as possible.

Uncle Wang decided to check the rear taillight himself first. He carefully examined the appearance of the taillight and found no signs of the lamp cover being broken or the bulb being obviously damaged. However, when he turned on the headlight switch, the rear taillight still didn’t respond. Helplessly, Uncle Wang could only drive the vehicle cautiously and slowly towards a nearby town, hoping to find a place to repair the electric vehicle.

Finally, in a corner of the town, Uncle Wang found an electric vehicle repair shop. The repairman, seeing Uncle Wang’s anxious expression, greeted him warmly. Uncle Wang described the malfunction of the rear taillight to the repairman in detail. After listening, the repairman immediately started checking the vehicle.

The repairman first checked the vehicle’s fuse because a blown fuse could cause the circuit to be interrupted, resulting in the rear taillight not working. He used professional tools to open the fuse box and checked each fuse one by one, only to find that none of them were blown. Then, the repairman checked the circuit of the rear taillight. He carefully traced the wires and found that there was no damage or short circuit in the circuit.

After a series of inspections, the repairman pinpointed the problem to the bulb of the rear taillight. He skillfully removed the rear taillight assembly, took out the bulb, and after a careful examination, found that the filament of the bulb had burned out, which was the reason for the rear taillight not working. The repairman explained to Uncle Wang that the bulb was a vulnerable part. After long-term use, the filament would gradually age and eventually burn out.

The repairman took out several different models of bulbs from the shop and introduced to Uncle Wang that these bulbs varied in brightness, lifespan, and price. Some bulbs adopted more advanced LED technology, with high brightness and a long lifespan, but they were relatively expensive. While some ordinary incandescent bulbs were more affordable, but their brightness and lifespan were relatively shorter. Considering that his electric four-wheeler was mainly used for short-distance daily trips and he didn’t have a particularly high requirement for brightness, Uncle Wang chose an incandescent bulb with a moderate price.

After deciding on the bulb, the repairman started the replacement. He first carefully installed the new bulb into the rear taillight assembly, and then installed the rear taillight assembly back in place, ensuring that each screw was tightened. After the installation was completed, the repairman turned on the headlight switch, and the rear taillight lit up instantly, with the bright light illuminating the road behind.

Seeing that the rear taillight was working normally again, Uncle Wang finally felt relieved. He thanked the repairman gratefully, paid the money, and then continued his journey to the countryside with his wife. In the afterglow of the setting sun, the rear taillight of Uncle Wang’s electric four-wheeler shone with a warm light, guiding them towards a beautiful distance.

This experience made Uncle Wang deeply realize the importance of the rear taillight for the safety of vehicle driving. He also reminded other owners of electric three-wheelers and four-wheelers to pay more attention to the vehicle’s lighting system at ordinary times, regularly check components such as the rear taillight, and repair or replace them in a timely manner once any problems were found, so as to ensure safe driving at night. From then on, Uncle Wang would habitually check the rear taillight before each drive, making his trips more reassuring.
