Description
The SureFire DS00 is the tail-cap that unlocks the full potential of your Scout Light. Instead of settling for one way to run your light, this dual-switch assembly gives you an integrated click on/off pushbutton right on the cap plus a receptacle for plugging in a remote tape switch. Both operate independently, so if you ever pop a tape switch cable or want a quick manual option, you've still got a fully working light. That kind of redundancy is exactly what you want on a duty gun or a serious home-defense build.
What the DS00 Brings to Your Scout Light
The housing is a two-piece, O-ring sealed design that swivels, letting you dial in the exact position of the click switch so it falls right where your thumb naturally lands. The whole assembly is waterproof, so rain, snow, or a dunk in a creek won't take your light offline. There's also a built-in system disable feature, which lets you lock the light out during transport or storage so nothing gets bumped on by accident.
Switch Compatibility and Remote Options
The DS00 receptacle accepts SureFire's ST07, SR07, and SR07-D-IT remote tape switches, all sold separately. That flexibility is a big part of why folks reach for this cap over a basic push-button tailcap. It's worth noting the DS00 works with most Scout Light WeaponLights but does not fit the Micro Scout Light Pro, so double-check your model before ordering.
A Popular Pick Beyond SureFire Bodies
One of the nice things about the DS00 is how widely it plays. Because it follows the Scout thread pattern, it also fits Modlite 18650 and 18350 Scout-pattern bodies, making it a go-to upgrade for anyone running a Modlite head on a Scout body. Machined and finished to the standard SureFire is known for, it's a simple bolt-on that gives you real capability without any fuss. Assigned NSN 5930-01-664-4488 and made in the USA.

Frequently Asked Questions
Which lights does the SureFire DS00 fit?
The DS00 fits most SureFire Scout Light WeaponLights, but it will not work with the Micro Scout Light Pro. Because it follows the Scout thread pattern, it also fits Modlite 18650 and 18350 Scout-pattern bodies. Check your specific model before ordering to be sure.
Does the DS00 come with a remote tape switch?
No, the tail-cap itself does not include a remote tape switch. It has a receptacle that accepts SureFire's ST07, SR07, and SR07-D-IT tape switches, which are sold separately. The integrated click on/off pushbutton on the cap works right out of the box without any add-ons.
What is the system disable feature on the DS00?
The system disable feature lets you lock out the light so it can't be accidentally turned on during transport, storage, or while it's slung on your back. It's a handy way to prevent dead batteries from a bumped switch. You simply re-enable it when you're ready to run the light.
Why choose the DS00 over a basic push-button tail-cap?
The DS00 gives you two ways to run your light. You get both an integrated click switch on the cap and a port for a remote tape switch, and they operate independently for built-in redundancy. If one fails, the other still works, which is a big deal on a duty or defensive setup.
