If it's really dark, you want to be able to read something and still want to see stuff - like stars- in the dark, you want to use a very low intensity red light.

And no, you shouldn't use one on the front of a bike because people will think you are a wrong way cyclist or they may not see the light until they have invalidated your third dimension.
