Xenon headlight focus adjustment method: Remove the screws of the xenon headlight assembly, then detach the bulb clip. After turning on the headlight, move the bulb upward and check against a wall to ensure the focal point is slightly above the cutoff line. Xenon headlights have high brightness, measured in lumens—the higher the lumen value, the brighter the light. Xenon lamps, also known as high-intensity discharge (HID) lamps, are metal halide lamps. They work by filling an ultraviolet-resistant quartz glass tube with various chemical gases, including xenon and other inert gases. A ballast then boosts the vehicle's 12-volt power supply to 23,000 volts instantaneously. Under this high voltage, xenon gas is ionized, creating a light source between the two electrodes.

What Causes Oil Filter Leakage?

The reasons for oil filter leakage are: a broken sealing gasket, not tightening it properly during installation, or overtightening which may cause the housing to crack. During engine operation, metal shavings, dust, carbon deposits oxidized at high temperatures, gummy deposits, water, and other contaminants continuously mix with the lubricating oil. The oil filter's function is to remove these mechanical impurities and gum, keeping the lubricating oil clean and extending its service life. An oil filter should have strong filtration capability, low flow resistance, and a long service life. Typically, the lubrication system is equipped with several filters of different filtration capacities: the oil strainer, coarse filter, and fine filter, which are connected in parallel or in series within the main oil passage.

How to Turn on High Beam in Mercedes-Benz?

Method to turn on high beam in Mercedes-Benz: Push the left-hand stalk towards the driver's side to activate the high beam. Release the stalk, and it will automatically return to its original position. Pull the stalk back to turn off the high beam and switch back to low beam. The high beam improves visibility and expands the field of view. On dark roads without streetlights, the visible range with high beam is much farther than with low beam alone, making it essential to use high beams in such conditions.

What does the 'V' on car tires indicate?

Car tires marked with 'V' indicate that the maximum speed under load is 240 kilometers per hour. This letter represents the speed rating of the tire. Tires with higher ratings are more expensive but offer better performance and safety. Typically, compact family car tires have lower speed ratings, while high-performance sports car tires have higher ratings. Spare tires are categorized into full-size spares and temporary spares. Full-size spares are identical to the original tires, whereas temporary spares are only meant for short-term use. Car tires are one of the most important components of a vehicle, as they directly contact the ground and, together with the suspension system, help absorb shocks during driving, ensuring comfort and stability. High-quality tires provide excellent grip between the wheels and the road, enhancing traction and drivability.
