one of my "lessons learned" from the 04/05 hurricane season if you use a large 3D MagLight... cable tie a split ring (keyring)to your large lights so you can clip it to you (I carry my keys on an external nylon belt clip, and have replaced the spring clip of my Maxpedition cell pouch with a similar nylon belt clip ... I have a habit of setting it down and not remembering where it is...also added rings to my SureFire 6P and Nitrolon G2 towards the button end to give more purchase if used with a thumb forward grip using a pistol...
