Review on Tsuinz Bike Light - USB Rechargeable Bicycle Front Headlight LED Light with 3 Modes and 2000mAh Power Bank - Easy to Install for Cycling Safety and Commuter Flashlight by Jon Bishop

Good product, requires slim phone case to attach clips. Fits Pixel 4 and Pixel 4 XL if they don't have a case or it's thin. The light is super, super bright. The beep is definitely NOT 130dB. Three different testers showed a maximum volume of around 90-100 dB. A little, that's ok, it's almost as loud as a regular bike horn. It's a bit annoying having to hold it down to change the sound, but the klaxon sound is the best!
