The Gear Locker reviews the Petzl STRIX VL headmounted light... "We had seen the pics of the STRIX online and it appeared you could also wear it on MOLLE vest, so we removed it from the head strap and sliding it out of its keyed base and noticed the clip on the underside on the lamp. we then clipped it to our Mayflower Plate Carrier and clipped it the upper chest area. During a training session, we found that the clip did not hold the light as securely as we wanted it to.
