The SureFire DS00 Scout Light Tailcap Switch, part number DS00-TN, is a push-button switching tailcap for SureFire Scout Light weapon lights in Tan, giving both momentary and constant-on activation from the rear of the light. SureFire lists this switch for the Scout Light M300, M340, M600 and M640 families, excluding the Micro Scout Light Pro.
The DS00 replaces the standard tailcap and carries no cable, so it is the choice when you want thumb activation at the light rather than a rail-mounted pad. It fits Scout Lights such as the M640DF Scout Light Pro rifle light, M640U Scout Light Pro rifle light, M640DFT Scout Light Pro Turbo rifle light and M640T Turbo Scout Light Pro rifle light, and the compact M340C Mini Scout Light Pro rifle light in Tan and M340DFT Mini Scout Light Pro Turbo rifle light in Tan.

Frequently Asked Questions
Which SureFire lights does the DS00 tailcap switch fit?
The SureFire DS00 Scout Light tailcap switch fits the SureFire Scout Light M300, M340, M600 and M640 weapon light families, replacing the standard tailcap. SureFire excludes only the Micro Scout Light Pro.
Does the DS00 give momentary or constant-on activation?
The SureFire DS00 Scout Light tailcap switch gives both: a light press holds the beam on momentarily, and a full press latches it constant-on.
Does the DS00 include a remote pressure pad?
No — the SureFire DS00 is the switching tailcap on its own. If you want a remote pressure pad as well, the DS07 and DS-SR07 pair a DS00 tailcap with a pad, and the UE-SR07 supplies a UE tailcap and pad together.
What is the part number of this DS00?
This SureFire DS00 Scout Light tailcap switch is part number DS00-TN in Tan.
Can I fit the DS00 myself?
Yes — the SureFire DS00 unscrews and screws onto a Scout Light body in place of the existing tailcap, with no tools required.
