In that case, your area lacks decent reflectors.
Reflectors available here are generally highly visible within a 140 to 160-degree sector. Lights, on the other hand, are often weak LEDs that are barely discernable in anything but unlit roads outside urban areas.
Lights are good for those cases where the other vehicle doesn't have a light pointed in your direction, but that's rarely the case in the real world.
