It’s only visible from the back, but more bikes are coming equipped with brake lights that strobe for a second when activated to get more attention. (We only have one rear brake light, compared to three on cars). And now it’s easy to find add-on helmet lights that also activate with the brakes. Not the all-rounder lighting you’re talking about, but early info seems promising.
I have tried many times to do exactly what you said, and I still am not getting the option to add a custom search engine.
Any advice you have is appreciated.
