I agree that most sight lights make the pins too bright for use in the evening, however the actual light used on this guy's SH light has 4 brightness settings. All the way from "burn my retnas out" to "barely visible". I have tried the light in the evening hours and the lowest setting provides the perfect amount of light to the pins. Not so bright that you are blinded, but just enough to keep the pins visible.

The issue I have with the extended fiber options is that during daylight hours the extra fiber length can cause the pins to be too bright as well.
