My Buying Guides on Auto Dim Rear View Mirror
When I decided to upgrade my car with an auto dim rear view mirror, I realized there were quite a few factors to consider to get the best product for my needs. Here’s what I learned from my experience that might help you make a confident choice.
What is an Auto Dim Rear View Mirror?
From my understanding, an auto dim rear view mirror automatically reduces glare from headlights behind you at night. This feature makes night driving safer and less stressful by preventing those harsh lights from blinding you.
Types of Auto Dim Mirrors
I found that there are mainly two types:
- Electrochromic Mirrors: These use a special gel that changes tint when an electrical current is applied. They’re very effective and common in newer models.
- Manual Dimming Mirrors: While not automatic, some models offer a night mode you switch on manually. However, I preferred the convenience of fully automatic dimming.
Key Features I Looked For
- Sensitivity Adjustment: I wanted a mirror that lets me adjust how quickly or intensely it dims because some conditions call for different levels of glare reduction.
- Integrated Features: Some mirrors come with built-in compass, temperature display, or even backup camera screens. I chose one with a compass because it helped with navigation on road trips.
- Power Source: I checked whether the mirror needed to be wired into the car’s power system or if it could run on batteries. I preferred a wired option for continuous operation without worrying about battery replacement.
- Size and Compatibility: It was important to me that the mirror fit my car’s mounting system and didn’t obstruct my view. I measured my existing mirror before buying.
Installation Considerations
I opted for a model with straightforward installation instructions. Some mirrors require professional installation, especially if they have integrated electronics. If you’re comfortable with DIY, look for plug-and-play options or those that use the factory mounting bracket.
Budget and Brand Reputation
I set a budget but was willing to spend a bit more on a trusted brand with good reviews. Reliability matters because a malfunctioning rear view mirror can be a safety hazard.
Final Thoughts
Choosing the right auto dim rear view mirror made a noticeable difference in my night driving comfort. If you want to improve your driving experience, consider these points carefully and select a mirror that fits your lifestyle and vehicle. Safe driving!
