Do LED Light Rear Covers Need Ventilation Holes for Heat Dissipation?

Generally, the dust covers of LED headlights require ventilation holes to assist in heat dissipation. Types of dust covers include: 1. Hard plastic material: Most rear covers of this material have sufficient internal space and require no special treatment. Simply reinstall after LED headlight installation. 2. Perforated soft rubber material: Typically used for H7 and H4 models. After securing the LED headlight clips, first install the dust cover before finally screwing the LED headlight into place. 3. Soft rubber material: Approximately 20% of vehicle models with this type lack adequate rear cover space, necessitating replacement or extension with longer dust covers to increase capacity.

How to Adjust the Rearview Mirror of a Volkswagen?

Here are the methods to adjust the rearview mirror of a Volkswagen: 1. When adjusting the rearview mirror angle, you can use the electric buttons inside the car, which are located on the left side of the steering wheel, to adjust the left and right rearview mirrors. 2. Adjust the center rearview mirror. Adjust the left and right positions so that the left edge of the mirror just cuts to the right ear of your reflection in the mirror, and the up and down positions should place the distant horizon in the center of the mirror. Key points for adjusting the center rearview mirror: place the horizon in the middle and your ear on the left. Position the distant horizon along the center line of the center rearview mirror, then move it left or right so that the image of your right ear is just at the left edge of the mirror. 3. Adjust the left rearview mirror. For the up and down positions, place the distant horizon in the center, and for the left and right positions, adjust so that the car body occupies 1/4 of the mirror's area. Key points for adjusting the left rearview mirror: place the horizon along the center line of the mirror, then adjust the edge of the car body to occupy 1/4 of the mirror's reflection. 4. Adjust the right rearview mirror. Since the driver's seat is on the left, it is not easy for the driver to grasp the situation on the right side of the car. Additionally, due to the need for roadside parking sometimes, the right rearview mirror should leave a larger ground area when adjusting the up and down positions, about 2/3 of the mirror. As for the left and right positions, adjust so that the car body occupies 1/4 of the mirror's area. Key points for adjusting the right rearview mirror: place the horizon at the 2/3 position of the mirror, then adjust the edge of the car body to occupy 1/4 of the mirror's reflection.

What to Pay Attention to When Parking a Car in an Underground Garage for a Long Time?

Pay attention to the protection of wipers and tires. The following is an introduction to underground parking lots: 1. Introduction: Sometimes underground parking lots also provide basic maintenance and minor repair services. Nowadays, large-scale underground space development includes parking lot planning, mainly because the total number of cars in cities is continuously increasing, while the corresponding parking spaces are insufficient. The phenomenon of 'difficulty in driving and parking' has become very common. Therefore, making full use of underground space to build parking lots plays an important role in alleviating urban traffic congestion. 2. Planning: Underground parking lot planning should be integrated into the overall urban planning, combined with the current situation and development of the city, coordinated with urban roads of different levels, and meet the parking needs of different scales, so as to regulate and control the traffic in the urban central area.

Does tightening the mixture screw on a motorcycle make it leaner or richer?

Turning it inward makes it leaner, and turning it outward makes it richer. For a 125cc carburetor's mixture screw, turning it inward makes it leaner, and turning it outward makes it richer. For engines below 125cc (excluding scooters), it's the opposite. This is because the 125cc models control fuel quantity, while those below 125cc (excluding scooters) control air. Additional information: For this type of carburetor's mixture screw, turning it clockwise makes it leaner, meaning the more you tighten it inward, the leaner it gets. Turning it counterclockwise makes it richer, meaning the more you loosen it outward, the richer it gets. Only small-displacement bikes like 90cc, 100cc, 110cc, or underbone 125cc carburetors become richer when turned clockwise. Most 125cc slide-type carburetors and almost all diaphragm-type carburetors become leaner when turned clockwise.

What is the difference between transverse deceleration and longitudinal deceleration?

Different appearances: transverse deceleration markings are rectangular dashed lines; longitudinal deceleration markings are diamond-shaped. Different directions: transverse deceleration markings are perpendicular to the direction of vehicle travel; longitudinal deceleration markings are parallel to the direction of vehicle travel. The standard term for deceleration markings is deceleration markings. Here are the specific details: 1. Transverse deceleration markings: White dashed lines set up in toll plaza, exit ramps, or other sections of the road where vehicle deceleration is required. They come in single, double, or triple dashed lines, perpendicular to the direction of travel. The transverse deceleration markings are a set of parallel white dashed lines designed to alert drivers to slow down. 2. Longitudinal deceleration markings: The longitudinal deceleration markings are a set of diamond-shaped dashed lines parallel to the lane dividing lines. At the starting position of the longitudinal deceleration markings, a gradient section is set up, where the diamond-shaped dashed lines gradually widen from narrow to wide, ranging from centimeters to centimeters. These markings are one of the new additions in the national standard for road traffic markings (GB78.-dao9). When vehicles pass through sections with longitudinal deceleration markings, drivers' subjective vision will perceive the lane gradually narrowing, prompting them to increase attention, actively take deceleration measures, and proceed slowly. This can effectively prevent drivers from applying sudden brakes when approaching the stop line. Pedestrians on crosswalks can clearly feel vehicles yielding, thus gaining a sense of safety, reflecting a harmonious traffic environment between pedestrians and vehicles.

Should I Keep Driving an Accident-Damaged Car or Sell It?

It is recommended to sell it. Accident-damaged cars directly affect driving safety. Definition of an accident-damaged car: An accident-damaged car refers to a vehicle that has suffered damage from non-natural wear and tear accidents, resulting in decreased mechanical performance and economic value. Generally, "accident-damaged cars" are those with structural damage. Additionally, flood-damaged cars and fire-damaged cars also fall under the category of "special accident-damaged cars." Methods to identify an accident-damaged car: Identification methods include exterior inspection, light inspection, insurance record checks, and interior examination. Conditions for quick accident handling: The conditions for quick accident handling are no personal injuries, property damage not exceeding the specified amount, no disputes among the parties involved regarding accident liability, the accident-damaged car being drivable, all parties involved having vehicle insurance, and the willingness of the parties to proceed to a designated location for damage assessment.
