Reconnect the neutral and live wires of the switch socket properly. You can distinguish between neutral and live wires using methods such as a test pen, multimeter, or wire color. Enhance heat dissipation by applying thermal coating on the lamp housing or other methods.

When I encounter flashing LED lights while driving, I immediately pull over to check for safety. Flashing indicates unstable circuitry, which could lead to sudden failure—especially dangerous at night, as it impairs visibility and increases the risk of accidents. My first step is to check if the fuse is blown by locating the corresponding headlight fuse in the engine compartment's fuse box and replacing it with a new one. If the flashing persists, I inspect the wiring connections for looseness, particularly at the plugs and lamp sockets, as prolonged vibrations can cause them to come loose. Poor grounding or excessive voltage can also cause LED flickering, so it's best to use a multimeter to test the battery voltage—if it's too high, the alternator may need repair. Avoid DIY fixes, especially on vehicles with modified wiring, as mistakes are common. For safety, I always address such issues promptly by visiting a professional repair shop to prevent potential hazards or cascading effects on other lights. As a routine, I also inspect bulb conditions and clean connectors every six months to prevent recurring flickering issues.

How to Determine if a Cigarette Lighter is 24V or 12V?

The most straightforward method is to use a multimeter to measure the voltage between the two terminals of the car battery or to measure the voltage between the center and the side of the cigarette lighter socket. The car battery will also have markings indicating the voltage. Vehicles with gasoline engines typically use 12V, while diesel engines use 24V. Most small and medium-sized cars have 12V batteries.

How to Adjust the Softness and Hardness of Motorcycle Rear Shock Absorbers?

Generally, excessive stiffness in shock absorbers is due to the motorcycle being new, as the mechanical components have not yet fully broken in. The situation will improve after the break-in period. You can adjust the hardness of the shock absorbers by changing the tire pressure, but the reduced tire pressure should still remain within the normal range. Consult a professional for advice. If modifications are allowed, consider replacing the shock absorbers with adjustable ones, such as coilover shock absorbers.

What to do if the sonar-off light is flashing?

This indicator light flashing indicates that the car's radar function is activated, and the radar signal can detect vehicles traveling in front, such as those within 200 meters. Once activated, the vehicle can continuously follow the car in front and maintain the current distance. The vehicle will accelerate or decelerate accordingly as the car in front speeds up or slows down.
