Well you wouldn't want to leave your light running in moon mode while it is stowed in a kit! You'd have to find it somehow to take it out of the kit, but after that you could charge up the GITD marker either with daylight (if daytime), or with the LED. There are also tritium markers, but they are on the expensive side for something like this, not so easy to buy, and they fade after some decades (H3 half-life=12 years).
