Simply install this switch ring in place of the standard aluminum retaining ring in the head of your MD2.  You'll then have two levels of light output with a twist of the head!  With the head tightened, the light will stay in high mode, even with quick flashing or signaling.  Loosen the head just a fraction, and the light will go into low mode.  You can keep it on low mode for quick flashing and signaling as well... it'll stay in low mode until you tighten the head again... simple!

Installation:   Remove standard aluminum retaining ring from head by unscrewing.  Place Malkoff Drop-In into head.  Install High/Low Bezel switch with tiny switch stem facing towards rear of flashlight.  That's it!
