One of my customers turned left and accidentally hit an "Invisible" ninja ebiker with his car, and rang me late last night. Cyclist was dressed in black, had no lights, no helmet, busted his head but survived. His head busted the side of my customer's car. His ebike was seen by the police before being stashed in the cyclist's brother's car boot, must have been a legal ebike? The cyclist had no insurance. My customer's insurance company will be chasing the cyclist for damage to the passenger side door. The cyclist could be lawyering up for a personal injury claim. One witness, no camera. There's loads of stealth ninja cyclists about, watch out. Hi-viz clad cyclists are also dressed for stealth IMO. Bright lights and lolliopos! And lights on those lollipops. A bike isn't dressed without frickin' laser beams.
This is on offer again at AliExpress at the mo. Bright (approaches brightness of one my 1800LM headlights), lasts hours, also functions as a power bank. I reckon it could be made red using heat resistant acetate sheet, but haven't opened mine up to try, because I already have a 1800LM red flasher. Two of these flashing up front and one made red flashing backwards, will gain a cyclist higher conspicuity. Annoyingly, three of these cost less than one of my 1800LM headlights. I shudder to imagine how my handlebar would look to drivers with 9 flashing at night.
