Overview

• ADAC examined 25 children’s high‑visibility vests and found 13 failed required reflectivity, while all five bought in brick‑and‑mortar stores met the norm.
• Performance on major platforms varied: of 16 vests bought via Amazon, 11 failed, and two of four from AliExpress failed, according to the reports.
• The club used a three‑stage procedure covering a visual check, an LED reference comparison, and photometric laboratory measurements, counting only models passing all three as safe.
• ÖAMTC highlighted visibility stakes, noting children in dark clothing are seen at about 25 meters versus up to roughly 150 meters with effective reflective strips, with a 50 km/h stop requiring over 28 meters.
• Advice for buyers includes checking for EN 17353 and using a phone flashlight from about three meters to confirm bright white reflection, with a separate IIHS study reporting that very reflective clothing can sometimes confuse vehicle sensors.
