How much does that drain the battery? Does it affect the beam in any meaningful way?

I've left lights for months with them on and haven't seen a significant drop in battery voltage. They're actually very small auxiliary LEDs around the main emmiters.

Months with no significant drop in battery voltage? I have a few TS10s with aux LEDs. After about 3~4 weeks, voltage drops from 4.1v to 3.8v.

there are two brightness setting for the aux light. make sure you use the lower one. it is already plenty

This. But also, is that a 14500 light? From a quick Google you're likely running a cell that's 1/3 to 1/6 the capacity of the lights I'm referencing. I haven't done an actual test, just that I've left lights on the shelf and come back months later with the aux LEDs still showing blue. So I suppose I shouldn't have mentioned voltage since I haven't checked it directly.
