Exterior rearview mirror

Types of exterior rearview mirror

Exterior rearview mirrors are available in various types, each designed to meet specific needs and preferences. Here are some common types:

• Standard mirrors

  Standard exterior rearview mirrors are the most basic type of mirrors. They have a flat glass surface that provides a traditional view of the area behind and beside the vehicle. Standard mirrors are often found on older vehicle models or as a cost-effective option on newer vehicles.

• Convex mirrors

  Convex exterior rearview mirrors have a curved glass surface that bulges outward. This design allows for a wider field of view compared to standard mirrors. Convex mirrors are particularly useful for spotting pedestrians, cyclists, and other vehicles in crowded urban settings. They are often used as supplemental mirrors attached to standard or convex mirrors.

• Heated mirrors

  Heated exterior rearview mirrors have integrated heating elements. These elements generate heat to quickly defrost or de-ice the mirror surface. Heated mirrors are especially beneficial in regions with cold climates or during winter months when ice and frost can obstruct visibility.

• Electrochromatic (auto-dimming) mirrors

  Electrochromatic exterior rearview mirrors are equipped with sensors that detect light from behind. When a vehicle approaches from behind, the mirror automatically dims to reduce glare. This feature enhances safety by improving visibility during nighttime driving or in low-light conditions.

• Power-adjustable mirrors

  Power-adjustable exterior rearview mirrors are electrically controlled. The driver can adjust the mirror angles using buttons or switches inside the vehicle. This convenience eliminates the need for manual adjustments and allows precise positioning for optimal visibility.

• Folding mirrors

  Folding exterior rearview mirrors can be manually or electrically folded inward against the vehicle's body. This feature is beneficial in tight parking spaces, crowded streets, or when transporting the vehicle on a trailer. Folding mirrors help prevent damage from accidental bumps or collisions.

• Blind spot monitoring mirrors

  Some modern exterior rearview mirrors come with integrated blind spot monitoring systems. These mirrors have sensors that detect vehicles in the blind spot area. When a vehicle is detected, an indicator light on the mirror surface illuminates to alert the driver. Blind spot monitoring mirrors enhance safety during lane changes and merging maneuvers.

Specifications and maintenance of exterior rearview mirrors

• Regular cleaning

  Regular cleaning is an important part of maintaining exterior rearview mirrors. Accumulated dirt, dust, and debris can obstruct visibility and affect the mirrors' performance. Using a soft, lint-free cloth and mild automotive cleaner or soapy water is recommended to clean the exterior rearview mirrors regularly. It removes accumulated dirt and dust from the mirror surface and housing. It is also important to clean the mirror housing regularly. The housing can accumulate dirt, moisture, and debris over time, affecting the mirror's performance. Users should also clean the mirror housing area where the mirror is attached to the vehicle. Water stains and dirt in this area can obstruct visibility and affect the mirror's performance.

• Inspect for damage

  Inspections for damage are important for maintaining exterior rearview mirrors. Damage, such as cracks, chips, and scratches, can obstruct visibility and affect the mirrors' performance. Regular inspections can detect such damage early. When inspecting for damage, users should carefully observe the mirror surface and housing for any visible cracks, chips, or scratches. They should also check for damage to the mirror housing, where the mirror is attached to the vehicle. Damage to the housing can affect the entire mirror's stability and adjustment.

• Proper adjustment

  Proper adjustment is important for maintaining exterior rearview mirrors. Proper adjustment ensures that the mirrors provide optimal visibility and safety. When adjusting the mirrors, users should ensure the following: The driver's side mirror is adjusted to display a small portion of the vehicle's side, allowing the driver to see the vehicle's side and rear traffic. The passenger-side mirror is adjusted to show more of the vehicle's side, allowing the driver to see the vehicle's side and rear traffic. Both mirrors are adjusted to minimize blind spots and provide optimal visibility.

How to choose exterior rearview mirrors

When selecting exterior mirrors, car dealers should consider several factors, including;

• Vehicle type and compatibility: The car's type, model, and year of make are crucial when choosing the correct exterior rearview mirrors. For instance, larger vehicles like trucks and SUVs need bigger mirrors for better visibility. Additionally, the mirrors need to be compatible with the vehicles' mounting points and the car's body where they will be installed.
• Visibility and adjustability: A key function of exterior rearview mirrors is to provide visibility to the rear and side of the vehicle. Therefore, dealers should consider mirrors that offer a wide view without blind spots. Additionally, the mirrors should be easily adjustable to suit different drivers' preferences.
• Mirror coating and housing: Exterior rearview mirrors are made of different coatings and materials. The coating on the mirror surface affects durability and visibility. For instance, some have a blue tint that reduces glare from sunlight and street lights. Moreover, the housing is available in a variety of materials, including plastic and aluminum. A good choice is materials that are corrosion-resistant and durable.
• Mirror type: Various types of exterior rearview mirrors are suitable for different preferences. For instance, while conventional mirrors offer a simple reflection, convex mirrors provide a wider field view at the expense of some distance. Moreover, heated mirrors are ideal for cold regions where ice and frost can build up on mirrors and distort visibility.
• Signal lights and auto-dimming features: Some exterior rearview mirrors have integrated signals lights that alert other road users when changing lanes. Additionally, auto-dimming features are important in reducing glare from the bright lights of the vehicles behind.

How to DIY and replace exterior rearview mirrors

Follow these steps if the exterior mirror needs to be replaced:

• Gather the required tools: Get a screwdriver set, trim removal tools, safety glasses, and gloves. These will be used during the replacement process. Also, get the new exterior rearview mirror to be installed.
• Prepare the vehicle: Park the vehicle in a safe and well-lit area. Ensure it is turned off, and the mirrors are not adjusted accidentally.
• Check the mirror: Understand how the current mirror is installed. Is it glued, bolted, or clipped on? This will help determine the best way to remove it without damaging the car.
• Remove the old mirror: If it is bolted on, use a screwdriver to remove the bolts. If it is clipped on, use a trim removal tool to loosen the clips. Be careful not to damage the mirror housing or the vehicle's paint. If it is glued, use a heat gun or solvent to loosen the glue and carefully pry the mirror off.
• Clean the area: Once the old mirror is removed, clean the surface where the new mirror will be mounted. This ensures a strong bond if it is glued on.
• Install the new mirror: Position the new exterior rearview mirror in line with how the old one was mounted (glued, bolted, or clipped). If it is glued on, apply a strong adhesive to the back of the mirror and press it firmly into place. Hold it for a few minutes to allow the glue to set. If it is bolted or clipped on, secure it tightly but avoid overtightening to prevent damaging the mirror housing.
• Test the mirror: Adjust the new mirror to the desired angle and ensure it is secure. Give the adhesive some time to dry if it was glued on before driving the car.

Q and A

Q: Are electric exterior rearview mirrors better than traditional ones?

A: Traditional exterior rearview mirrors are manually operated. They are less convenient and harder to adjust, especially for larger vehicles. Electric mirrors are easier to adjust from inside the car, which is more convenient and safer. Electric exterior rearview mirrors are also better in terms of aerodynamics. They can also be designed smaller, giving vehicles a more stylish look and reducing drag. Electric mirrors are easier to adjust, and the size can be made smaller, which is more convenient.

Q: What is the difference between a convex and a flat mirror?

A convex mirror has a rounded surface that bulges outward. It helps to see a wider area, but objects in the mirror appear smaller. This type of mirror is good for blind spot coverage. A flat mirror has a completely even surface. It reflects objects in the same size as they appear. Flat mirrors provide accurate representation but cover less area. Some exterior rearview mirrors combine convex and flat mirrors to give drivers wider coverage and accurate blind spot information.

Q: Why are exterior rearview mirrors important?

A: Exterior rearview mirrors help to see vehicles, pedestrians, and objects behind and beside the car. They allow drivers to change lanes, reverse, and navigate tight spaces safely.
