Hello all. I was wondering if anyone else was having this problem. I turned on my Quark 123^2 and noticed the moonlight mode would not come on, neither would the low mode. With the head loosened it cycles between: Medium Medium High High Beacon SOS Beacon. Then with the head tightened it goes Max , Strobe. The two lower modes have somehow magically been erased. This isn't a tactical model either it's the plain jane 123^2. I'm emailing 4Sevens; but wanted to see if anyone else on here had a problem like it or the same problem.
