Hey guys!!!!Just woundering, how do you identify a dying light? (i have an E2d) And when do ya know that it needs replacing. Also, just wondering if the juice of the batts will drain out if u keep the tailcap tight(my E2d has no witness marks and my friend told me that if u keep don't keep the tailcap in lockout position, it'll cost u a pair of batts). Thanks /ubbthreads/images/graemlins/icon23.gif
