What lights to use when driving at night under poor lighting conditions without street lights?

When driving at night without street lights and under poor lighting conditions, you should turn on the high beams. High beams are generally suitable for motor vehicles driving at night on roads without street lights or with poor lighting, such as on dimly lit national highways or expressways. In urban areas where lighting is good, low beams must be used. Below is relevant information about high beams: Concept: High beams refer to adjusting the intensity of light based on the distance of the filament when driving at night. Effect: High beams can improve visibility and expand the field of vision. During nighttime encounters with oncoming vehicles, high beams can cause temporary blindness to the opposing driver. The duration of this blindness varies depending on the driver's own vision and the surrounding environment, but it typically lasts at least 2 seconds. During these two seconds, the driver is essentially driving with their eyes closed, significantly reducing their ability to observe pedestrians and oncoming traffic.

When I first started driving, I used to struggle with this issue too. On unlit roads at night, you absolutely must use high beams! Low beams only illuminate about 30 meters ahead, while high beams can reach over 100 meters - especially crucial on those bumpy rural roads. But you've got to watch for oncoming traffic - switch to low beams as soon as you spot headlights in the distance, or you'll blind other drivers. Remember to switch at least 150 meters before meeting another car - last year I tried switching at 200 meters and the other driver even waved in thanks. Keep alert when that blue high beam indicator lights up on your dashboard - I got caught by a traffic camera last time for failing to dim my lights when meeting another car, costing me 300 yuan and 1 penalty point. That really hurt!

Having driven night freight routes for ten years, this kind of road condition is a daily sight. The most practical approach is using a combination of high beams and fog lights—fog lights illuminate the ground to spot road cracks and small stones. During rainy or foggy weather, lowering the high beams a bit makes driving safer. Our domestic pickup trucks come with a headlight height adjustment knob, which is very handy. Avoid retrofitting xenon lights—a colleague got fined just last week. Never aim high beams directly at road signs; the glare from reflections is extremely dangerous. Once, on a curve of National Highway 318, I almost crashed into a mountain because high beams reflected off a signboard. Since then, I always drive with amber polarized glasses.

The principle of automotive lighting is actually quite scientific. On unlit roads at night, the high beam mode must be used. In terms of optical design, its parallel light beam can illuminate up to 150 meters, and the angle is precisely calculated. However, it's important to note that automatic high beam systems equipped in models like Volkswagen and Toyota have triggering delays, so manual switching is recommended on mountainous curves. When retrofitting LED lights, pay attention to heat dissipation—last year, while helping my nephew repair his car, I found that aftermarket lights had deformed the lens due to overheating. Tesla's matrix headlights, on the other hand, are quite impressive, capable of zoning and shielding the light area of oncoming vehicles.

Safety first is the iron rule. In this environment, you must use high beams, as low beams have too short of an illumination distance—equivalent to only seeing 3 seconds ahead at 70 km/h. I remember last winter night on a provincial highway, I couldn't brake in time after spotting collapsed rocks on the road because I hadn't switched to high beams promptly. It's best to pair them with parking lights, making it easier for trailing vehicles to judge your position. In heavy fog, switch to a combined tactic: high beams + front and rear fog lights. Nowadays, new cars come with automatic headlights, which is very convenient—my Geely Xingyue's headlights automatically turn on when unlocked at night to light the way.

Tested various lighting effects firsthand. Regular halogen high beams are sufficient but have a short lifespan, LED lights are whiter and brighter but poor in rain and fog penetration, while laser headlights are excellent but too expensive. Practical driving requires some tips: keeping the windshield clean is crucial, as oil film can reduce light transmission by 20%. I use an oil film remover to clean the glass weekly, and the nighttime visibility has improved significantly. For modifications, it's advisable to choose certified products like Osram Night Breaker. Last year, I bought cheap off-brand bulbs to save money, and they experienced light decay in just two months—driving on the highway felt like driving blind, which was terrifying.
