opersan 4 cm Width 10 Meters Length Decorative Purpose Prismatic Honeycomb Patterned White Reflective Strip Tape

Hello, the product you are reviewing is not a 'glow in the dark' (phosphorescent) product. This product has reflective properties; that is, it does not emit light by itself in complete darkness, but requires a light source (such as a flashlight, vehicle headlight, etc.) to shine on it. when it is hit, it strongly reflects the light back. We present it for your information and wish you pleasant shopping.

Hello, first of all, thank you for your interest. The 4 cm wide product you are asking about has a high reflection feature and shines strongly when light hits it during night drives; it is ideal for increasing visibility and for accessory use. However, in order for your vehicle to pass the TÜV inspection, it is necessary to use products that are 5 cm wide and ECE 104 certified, as required by regulations. If you're looking for inspection compliance, we recommend choosing our 5 cm wide 'ECE 104 Certified' reflector strips available in our Trendyol store. We wish you safe driving."
