Improve safety by removing blind spots: these blind spot mirrors give a wider view of both sides of your vehicle so you can see approaching cars and bicycles earlier, helping to reduce the risk of collisions during lane changes and turns. High-quality construction: made with an ultra-thin glass lens for clear, distortion-free reflection. The mirror is durable and waterproof for reliable performance in varied weather conditions. Universal compatibility: designed to work on cars, trucks, SUVs and RVs. Use it alongside factory mirrors to expand your field of view without replacing existing equipment. Simple, damage-free installation: mounts on a car window or rearview mirror using included double-sided tape. Install directly — no drilling or tools required — and remove cleanly when needed. Lightweight, low-profile design: sits discreetly on the glass or mirror edge to improve visibility without obstructing your sightline. Practical use scenarios Highway lane changes: see vehicles in adjacent lanes earlier to make safer lane changes at speed. Urban driving and parking: detect cyclists and pedestrians approaching from behind when navigating crowded streets or pulling into tight spaces. Towing and hauling with trucks or SUVs: monitor trailer sides and blind areas to reduce guessing while backing or turning.
