Illumination

I've been rocking my old SureFire E1B backup light as a part of my EDC (every day carry) loadout for quite some time, but while wanting to try out using the Thyrm Switchback with it I was sad to see this model was not supported. Since Surefire doesn't make the E1B anymore this made sense design wise on the Switchback and ended up as a good excuse to try out the EB1. (Yes the names are a bit confusingly similar)
