Grandad, blinded any drivers yet? hope so
For a long while now I've been trying to work out how to add more lights to my bike, ones that aren't for my extra visability along dark roads/paths but ones for other road users to see, but they have to be stealthily added so like my reflector lights it doesn't appear like they're there when not powered up.
And today I came up with the perfect solution: LEDs in the plastic caps covering the bolts holding the wheel axles. White for the front and red for the rear, with the tops filed down to give a really wide angle, then I'll have full 360 degree visability with my lights
