Methods for safely using car lights: 1. Position lights: Also known as clearance lights, position lights are used during evening driving to allow other drivers to judge the size and width of the vehicle ahead; 2. Low beam: The low beam and high beam of a vehicle are collectively referred to as headlights. The original vehicle's low and high beams cannot be turned on simultaneously. According to requirements, the vehicle's lights should be turned on along with the street lights, meaning that when street lights are on, the low beam must be turned on. The low beam has an illumination distance of about 30 to 40 meters; 3. High beam: The high beam has a higher angle of illumination, thus covering a longer distance, with more concentrated and brighter light. In principle, high beams should only be used when there are no lighting facilities and no oncoming vehicles. Otherwise, it can severely interfere with the vision of other drivers and even cause traffic accidents; 4. Turn signals: Turn signals are used to indicate that the vehicle needs to turn. When turning, the turn signal must be activated in advance, and the turn should only be made after confirming there are no vehicles approaching from behind. Never turn immediately after signaling without checking the rear situation. When overtaking, activate the left turn signal in advance and only overtake after confirming it is safe. If a vehicle behind intends to overtake, you can indicate by activating the right turn signal to allow it to pass.

Always familiarize yourself with the position of the light switches before driving. I make it a habit to twist the switch before setting off to confirm the light status. Low beams are essential for nighttime driving, and you must switch back to low beams at least 150 meters before meeting another car; otherwise, you could temporarily blind the other driver. In heavy rain or fog, remember to turn on the fog lights along with the low beams, but avoid using high beams as the reflection off the water and fog can reduce visibility. If you need to stop temporarily due to a breakdown, immediately turn on the hazard lights to warn other drivers. Another detail: when reversing in a residential area without streetlights at night, it's best to turn on the interior light and brake lights so pedestrians can notice you from a distance. Use the turn signals at least 3 seconds in advance—don’t wait until you’re turning—as this gives following drivers crucial reaction time.

I pay special attention to lighting combinations during long-distance drives. Using high beams on highways at night is fine, but you must immediately switch back to low beams when you see a car ahead in the rearview mirror or an oncoming vehicle. Turn on your headlights two seconds before entering a tunnel—don't wait until you're inside to avoid being caught off guard. Flash your high beams twice before entering mountain road curves to alert oncoming traffic, especially on sharp bends with many blind spots. Turn on your lights at dusk before it's completely dark, as this is when misjudgments most easily occur. Never use hazard lights instead of fog lights in rainy conditions—the frequent flashing of hazard lights can actually interfere with the following car's distance judgment. Also, be cautious with lighting modifications; don't swap in ultra-white bulbs just for looks, as overly bright scattered light can be a hazard to others.

I make it a must to check the lighting system during every annual . The gradual dimming of aging bulbs is hard to notice, so I regularly compare the brightness uniformity between left and right lights against a white garage wall. For brake lights, I either ask a friend to press the brake pedal while I check from outside, or observe the reflection when reversing near a shopping mall's glass wall. Yellowed lamp covers need timely polishing, and moisture-invaded light assemblies require resealing. I always keep spare bulbs and fuses in the trunk - especially important for vintage car owners taking long trips. If only one side lights up suddenly, it's likely a blown fuse - DIY replacement is much faster than calling a tow truck. Never drive with failed lights - the danger level skyrockets in darkness.

Mastering light switching for different road conditions is essential. You must manually turn on your lights before entering a culvert during daytime, as automatic headlights often have delays in tunnels. Turn off high beams when following closely, otherwise your lights will flood the leading car's rearview mirrors. Using the right turn signal is clearer than hazard lights when temporarily picking up/dropping off passengers roadside, especially near school zones. When overtaking, flash your left turn signal with high beams three times quickly to send a clear signal. For tricycles without dedicated turn signals, supplement with hand signals and frequent brake light flashes. For older cars with blurry reversing cameras, turning on rear fog lights while reversing improves rear visibility - this trick is particularly practical.

Nowadays, more and more cars come with adaptive high beams, but don't too much on technology. The system sensors may fail when covered by mud or water, so pay attention to the dashboard warning lights. When the system automatically switches between high and low beams, observe whether the beam height suddenly rises, and intervene manually if necessary. Be extra cautious on rural roads, as the automatic system may mistake reflective roadside signs for oncoming vehicles and suddenly dim the lights. In areas with dense fog, it's safer to turn off the automatic mode and manually turn on the fog lights along with hazard lights. After upgrading to matrix headlights, recalibrate the height; some repair shops may overlook this step, leading to uneven road illumination.
