I received this copper TS10 a few days ago and I finally got some time to do that mod that I also do when I receive a TS10.
When shipped, the aux leds (regardless of colour) are always too bright and drain the battery too fast for my liking.
For the orange aux, I added a 510Ω resistor, which dims it down to a comfortable brightness IMO. I don't have the numbers right now but the battery will also last much longer in high mode. Here are some pictures to show the difference.
High mode: left - no resistor added, right - 510Ω resistor added

Low mode: left - no resistor added, right - 510Ω resistor added

High mode after modding: 510Ω resistors added to both lights, much better

Very nice! I always just live with low aux on the TS10 and no aux on lockout to avoid the high drain. Not as pretty but it works well enough.
Any tips for getting the bezel off easily? I would like to to lego mine together for an Al/Cu look.
