Bus drivers routinely thank me for working with a Flash Light to acquire attention in the evening. Some situations when its rainy, and dark, visibility occurs. I can't manage to miss my bus ride so, I carry two Flash Light, one on my key chain, and a backup in my backpack. I start signaling the bus, as soon as I see it following. I have seen people just use LED based flashers, in order to those attached to bicycles, more efficient. Also, one more thing keep your bus pass in a light-weight to accessible location, have it ready before boarding public transit. I keep my bus pass in the luggage tag holder. I attach the bus pass holder to my backpack having a plastic tie strap, this insures public transit pass isn't getting lost, but is in order to understand access.
