Put a screw down cap on the rear of the light, connected to the negative contact with the QTC in between, so that you can adjust the brightness without crushing the battery. Basically, put the qtc pill in the rear of the light, behind the negative contact instead of in front of it. This would also allow the light output to be adjusted before the head is engaged. If that makes sense.
Only issue would be isolating the negative terminal. Just make it out of plastic with an aluminum/copper insert.
