Well definitely not the tailcap clicky. It seems to be the selector ring. Just subtle pressure makes it go on and off.
Yeah, that always seemed likely. I suppose you could check in the modders forum, to see if anyone has any advice for opening up the head. Otherwise, sounds like you will have to deal with Jetbeam's warranty service.

Try a little experiment if you have a small magnet handy: try moving a magnet around the control ring to see if you can get the light to come on. I've done this on mine and found the embedded magnet in my ring with this method. I was able to turn the light on with the ring set to Standby using the handheld magnet. It worked regardless if I got the polarity of the magnet right or wrong. It almost sounds like the previous owner unscrewed the head below the bezel ring, separating the two parts that retain the selector ring. I wonder if the magnet fell out or the lower half is misaligned from the top half?

The more I think about it the more it seems that the head unscrewing is the issue. The circuit board with the hall sensors is attached to the lower part while the part with the words, High, Medium, Low, is separate from it. It would appear that the detents are on the part with the words so if they're out of alignment the magnet in the ring may not come close enough to a hall sensor to turn on the light. Try turning on the light, place the retaining ring on Low then tighten the two halves and see what happens. I'm guessing that the light will come on first on High then Medium then Low.

Yeah, the magnet wasn't doing anything. The twisting seems more likely the issue.
There seems to be some play in the head, just a tiny bit, just slight pressure and the light comes right on. Just seems like a bad connection.

Curious if any one has completely taken this light apart? Maybe I just need to put it back together with stuff lined up correctly....

Taking apart the RRT-2:

1) remove the bezel ring, lens, O-ring, reflector, and black lens centering ring from the front of the light.
2) desolder the two wires from the MCPCB and remove the MCPCB from the light.
3) unscrew the aluminum heatsink and remove it.
4) unscrew the two small screws holding the driver board from the body.

This is as far as I've gotten with mine. I was unable to loosen the two halves of the head that retains the selector ring. The driver board is attached to the lower part of the head the selector ring is indexed on the upper. If they go out of sync then it'll not work right.

tbarb169, rotating a small magnet around the selector ring didn't turn on the light? It almost sounds like your head's upper part and the lower part are out of sync by 160+ degrees and the magnet is not getting near enough to the hall sensors to turn the light on. To locate the magnet, rotate the ring until the arrow points at "High" and the magnet will be located under the scallop sitting over "Standby". At least that's where I found mine.

PPC, thanks for the info. I will try the magnet again tonight before I try taking the light apart. Not sure if i am going to go to the extreme of unsoldering the light.

Well I finally got around to taking the light apart last night. Turns out the two screws by the led were not tight. I completely took it apart, cleaned it and relubbed it. Put it all back together and worked like a charm.

Only downside was a little scuffing of the finish since I had a hard time getting the light apart. Oh well, at least it works now!

"The light comes on in a very fast (and very annoying) 21.8 Hz strobe, followed by a just slightly less annoying 15.2 Hz, and then a 6.6 Hz and 5.5 Hz strobe. As I mentioned, each frequency lasts for about 0.5 secs, and then the whole thing repeats."

It would probably be a lot more effective if it went 21.8 - 6.6 - 15.2 -5.5 Hz
Oh well

Sorry, I did not take any pictures. I don't think i even realized that I fixed it until i was putting it back together. When i tightened the screws, i recalled that they were not very tight when i was taking them out. Once it was all back together, i dropped the battery in and it was like it was when i first received it.

If the manufacturer can't help, flashlightlens.com may be able to supply something of the right size. You would just have to provide very exact measurements of the diameter. Good luck!
