Spoke reflectors, as far as I know, often come in two colors: yellow and white.
Is there a convention as to which one should go on the back wheel and which one should go on the front wheel?
For instance, on cars, front lights are suppose to emit white or amber light, and rear lights are supposed to emit red light. Is there some convention for bikes as well, like "Front = White, Rear = Yellow"?
I am aware of this post, but I don't think there is any legal obligation as to which goes where. So, is this just a convention, and if yes, which one?
