Classic Surefire Model 660 Universal System Weapon Light. Includes the Surefire M10 Weaver / Picatinny mount and tape switch tail cap and click switch. Good used condition; normal use marks on it. Works perfectly. Lens is clear and in good condition with several scratches on it but do not affect function or light throw at all. 

The tape switch pad is in good condition and works perfectly but has started to crack along the edges. There are no cracks in the wire, just the little plastic/rubber part at the end that covers the wire has come off - it does not affect the wire at all. I have also included a Surefire Velcro attachment pieces. See pics. This is an authentic Surefire / Laser Products light.

It has a Surefire P60 incandescent bulb in it. It uses two CR123 batteries (not included).
