It is a circular glass cover, resembling a convex lens like a magnifying glass. The function of a car light lens: The car light lens can reflect the scattered light of the bulb into parallel beams, significantly enhancing the brightness and ensuring sufficient illumination within a range of 150-400M in front of the car. At the same time, in the low beam state, the light does not diverge, but provides good ground illumination without causing glare or affecting the normal driving of oncoming vehicles. Types of car light lenses: Lenses are divided into two types: single-beam lenses and dual-beam lenses. A single-beam lens controls one bulb and is a dedicated product, with separate high and low beams. A dual-beam lens can switch between high and low beams through an internal shutter.

The lens is the transparent cover on the front of a car's headlight, resembling a semi-circular plastic shield that covers the bulb. It feels smooth to the touch and is often made of polycarbonate, which is impact-resistant and refracts light. After years of driving, I've noticed it usually has small ripples or grid patterns on the surface to control light direction and avoid blinding oncoming drivers. Located on both sides of the front bumper, it easily collects dirt or turns yellow over time. Severe oxidation can make it hazy and reduce visibility at night. I always use a soft cloth and water wax for cleaning to maintain brightness and safety. Avoid using hard brushes to prevent scratches. When upgrading to a new lens, choose one with high transparency for a cooler look and better durability.

The lens in a car's lighting system plays a focusing role, resembling a transparent shell, mostly shaped like a protruding hemisphere. The material is typically lightweight plastic, with micro-textures on the surface to evenly disperse light. I enjoy studying automotive lighting technology and have found that lens design can reduce glare issues. Compared to exposing the bulb directly, it focuses the beam more centrally on the road, improving visibility. Some newer models feature more refined lenses with UV-resistant coatings to prevent aging. The installation position effectively protects the internal bulb from impacts. During cleaning and maintenance, avoid using acidic cleaners to prevent damage, which can quickly degrade performance. Overall, this small component significantly enhances energy efficiency and driving safety.

The lens condition is directly related to driving safety. It's essentially a transparent plastic cover positioned in front of the headlight. Once it becomes cloudy or cracked, the light weakens or even scatters. I often encounter heavy rain while driving at night, and only a clear lens ensures proper road visibility. Prolonged exposure to sunlight can cause oxidation and yellowing, requiring timely polishing for restoration. Neglecting maintenance may increase accident risks, as impaired visibility affects judgment.

Where is the cigarette lighter fuse located in the new Hyundai ix35?

Hyundai ix35 cigarette lighter fuse is located in the fuse box under the driver's compartment. Here are the specific details about the fuse box: 1. The Hyundai ix35 fuse box is an overcurrent protection switch, whose main function is to control circuit operation. There are many circuits in a car, and fuses serve to protect these circuits. When the circuit temperature is too high or the current is too large, the fuse will blow to protect the circuit. 2. The car fuse box contains many fuses and relays. When a fuse blows, certain functions of the car will be affected. After a fuse blows, it needs to be replaced with a new one. 3. When replacing a fuse, use a special clip to remove the fuse. The fuse box in the engine compartment is generally located near the battery, while the fuse box in the cabin is usually located in the main driver's position or inside the glove compartment on the passenger side.

A Kettle Appears on the Car Dashboard?

The kettle icon on the car dashboard is actually the engine oil pressure warning light, usually displayed in red with a drop of water at the spout. This symbol indicates whether the oil pressure is normal. Here are the reasons why the oil pressure warning light might appear: 1. Insufficient oil volume, which reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. 2. Overheating of the engine, which can thin the oil, causing it to leak excessively through the clearances and resulting in reduced oil pressure. 3. Clogged oil filter or oil suction screen, which can also decrease oil pressure. 4. Incorrect oil selection: Using the wrong oil or an inappropriate grade can lead to increased leakage due to low oil viscosity during engine operation, thereby reducing oil pressure.

What is the normal temperature of car coolant?

The normal temperature of car coolant is 90 degrees Celsius. The functions of coolant are: 1. Prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather parking; 2. Prevent metal parts from corroding and rubber components from aging; 3. Reduce scale formation to avoid clogging circulation pipes and affecting the cooling system's heat dissipation function; 4. Prevent the engine water temperature from becoming too high, ensuring the engine operates at normal working temperature; 5. Provide lubrication for the water pump thermostat and other components. The method for replacing car coolant is: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze; 2. Flush the engine cooling system; 3. Add new antifreeze when the engine is cool, filling it to the higher mark position on the radiator.

What's the reason for the fuel pump not supplying oil and the car not starting?

Here is the relevant introduction about the fuel pump not supplying oil and the car not starting: 1. Fuel quality issue: After disassembly, water and mud were found in the fuel tank. Using such fuel will inevitably damage the car. Therefore, car owners are reminded to always refuel at reputable gas stations. When traveling, you can use a gauze wrapped around the fuel nozzle to filter out impurities. 2. No antifreeze added: Some car owners add water or low-quality antifreeze to their cars, resulting in the entire water system freezing in extremely cold winter conditions, causing the engine to crack and the car water pump to fail, making the car unable to start and damaging other engine components. 3. Excessive vehicle carbon deposits: Excessive carbon deposits in the vehicle can also cause the car to not start. The solution is to frequently drive at high speeds to reduce carbon deposits.

What are the causes of skidding in a flat-flow pool truss vehicle?

Skidding in a flat-flow pool truss vehicle may occur due to excessively slippery road surfaces. Solutions for skidding in a flat-flow pool truss vehicle: Gradually and steadily release the brake pedal until all four wheels regain traction, avoiding pressing the clutch pedal; prevent wheel skidding; after stabilizing the vehicle's direction, straighten the steering wheel; smoothly press and release the brake pedal to reduce speed without locking the wheels; monitor road conditions ahead and adjust speed promptly; observe road surface conditions; always be aware of other vehicles' driving conditions; ensure tires, brake contact, steering system, and other components are in good working order. Safety tips for driving a flat-flow pool truss vehicle: Aside from weather and road conditions, skidding is often caused by driving too fast or lack of concentration; a major skidding taboo is to avoid slamming on the brakes.
