Didn't know this thread was still around. The HO-A2 has been working fine except when you lightly press the switch and there's a half dim beam coming out the front.
That's a sign the batteries are depleated. The A2's regulator does that, it's quite fussy about voltage, even apparently good batteries can produce that half powered glow. My 4 square sided A2-BK did that. Haven't had the same problem with my newer round sided one.
