4. Ignition Control Module: The ignition control module is a computerized component that controls the timing of the spark and ensures that the spark plugs fire at the right moment in the Engine Performance's combustion cycle.

Introduction
Air filters may not seem like the most exciting topic, but they play a crucial role in ensuring the air quality in your home is clean and healthy. In this article, we will discuss the importance of air filters, how they work, and why you should pay attention to their maintenance.

1. Incandescent bulbs: These traditional bulbs produce light by heating a filament inside a glass bulb. They are available in different shapes and sizes but are less energy-efficient compared to other types of lighting.
2. Fluorescent tubes: Fluorescent lighting is commonly used in commercial spaces due to its energy efficiency and long lifespan. These tubes produce light by exciting mercury vapor with electricity.
3. LED (Light Emitting Diode) lights: LED lights are the most energy-efficient and long-lasting lighting option available today. They produce light by passing an electrical current through a semiconductor material.
4. Halogen bulbs: Halogen bulbs provide bright and crisp light, making them suitable for task lighting. However, they are less energy-efficient and have a shorter lifespan compared to LED lights.
5. Smart lighting systems: Smart lighting systems allow users to control and customize lighting settings using a smartphone or voice commands. These systems offer convenience, energy savings, and customization options.

If your wheel bearings do require replacement, it is best to have the job done by a professional mechanic. Wheel bearing replacement involves removing the wheel, brake caliper, and hub assembly to access the bearings. Attempting to replace wheel bearings without the proper tools and expertise can result in serious damage to your vehicle.

Like all vehicle components, wheel bearings can wear out over time and require replacement. Recognizing the signs of wheel bearing issues can help prevent potential safety hazards and costly repairs. Some common signs of wheel bearing problems include:

Types of Air Filters
1. Fiberglass Filters: These are the most common and affordable type of air filters. They are effective at trapping larger particles but may not be as effective at capturing smaller particles.

Conclusion:
Electrical and lighting systems play a crucial role in providing power and illumination for buildings of all types. Understanding the basics of these systems, including key components, types of lighting fixtures, and installation considerations, is essential for ensuring safety, efficiency, and functionality. By following best practices for installation, maintenance, and upgrades, you can create a safe and energy-efficient environment with well-lit spaces for work, leisure, and everyday activities.

The wiper motor is an electrical device that powers the windshield wipers on a vehicle. It consists of an electric motor that generates the rotational movement required to actuate the wiper arms back and forth across the windshield. The wiper motor is typically located under the vehicle's hood, near the base of the windshield, and is connected to the wiper linkage that moves the wiper blades.

When you turn the key in the ignition, the battery sends a low-voltage current to the ignition coil. The ignition coil then amplifies this current and sends a high-voltage current to the spark plugs through the distributor or ignition control module. The spark plugs create a spark that ignites the air-fuel mixture in the combustion chamber, resulting in the engine starting and running.

When the driver activates the wiper control switch inside the vehicle, an electrical signal is sent to the wiper motor. The motor then converts this electrical energy into mechanical energy, causing the wiper arms to move. The motor operates at different speeds depending on the setting selected by the driver - typically, there are intermittent, low, and high-speed settings available.

Why is wheel alignment important?
Proper wheel alignment offers several benefits, including:
1. Improved vehicle handling: Correct wheel alignment ensures that your vehicle responds promptly to steering inputs, making it easier to control and maneuver.
2. Enhanced safety: Misaligned wheels can cause your vehicle to pull to one side, increasing the risk of accidents, especially in emergency situations.
3. Extended tire life: Wheel misalignment can cause uneven tire wear, leading to premature tire replacement and increased maintenance costs.
4. Better fuel efficiency: Misaligned wheels can create additional resistance, forcing the engine to work harder and consume more fuel.

Types of wheel alignment:
There are three main types of wheel alignment that technicians typically perform:
1. Toe alignment: This involves adjusting the angle of the tires inward or outward when viewed from above. Toe alignment ensures that the tires are parallel to each other and pointing straight ahead.
2. Camber alignment: Camber refers to the angle of the wheel when viewed from the front of the vehicle. Proper camber alignment ensures that the tire is sitting flat on the road surface.
3. Caster alignment: Caster angle measures the steering axis' tilt when viewed from the side of the vehicle. Caster alignment affects the vehicle's stability and steering response.
