ModButton Lite is a smaller lighter weight cousin to the original ModButton. The switch features the same momentary only activation as the original ModButton. It also features the same high power cable and switch from ModButton but in a slightly smaller package without the integrated mount. The switch is made from injection-molded plastic and fully potted to ensure a durable long lasting switch.

ModButton Lite utilizes a patented Unity Tactical design which supports power delivery needed by the next generation of high output weapon lights. A Unity built Surefire® compatible cable lead allows ModButton Lite to be backwardly compatible with all Surefire® Arisaka and Modlite Scout bodies as well as Surefire UE and DS00 tail caps. If constant on is a requirement we recommend using a Surefire DS00 tail cap which can be found here.

One problem that exists today is older legacy switches are not able to pass the current needed to run current and future generation lights. These older switch designs do not allow Modlite light heads to run at full power.  Typically these switches reduce output by 15-20%. ModButton Lite utilizes an updated plug design as well as improved electronics that allow the Mod Button Lite to output at full power so all the lumens and candela can be put to good use.

ModButton Lite is waterproof to 1 meter for 30 minutes and features more durable buttons than many competing pressure switches on the market.

The package includes the switch PIC mounting rail and mounting hardware only. An MLOK adapter kit will be available at a later date.

    The lite version is perfect. You can mount it anywhere your heart desires and feels great on the hand. And of course Big Tex was incredible with their lightning fast shipping and always better than the competition’s pricing. My go to store from here on out! Thank you Big Tex!

    Great product, great dealer, super fast shipping. What more can you ask for? Works great!

    Small footprint for more mounting options. Button press feels positive. Works well for shorter rails.

    I held off on the original Modbutton because I wasn’t particularly interested in an integral mount. When I saw the Modbutton Lite, it was just what I was looking for. It is slightly brighter than my SR07, and takes up much less rail-estate. The button is much more tactile than the SR07 and I don’t miss the constant-on. The cable is the perfect length, and I love how it clamps onto the rail, rather than just snapping over it like the SR07, and I feel comfortable without ranger bands or electrical tape securing it to the rail.

  5. connorppowell (verified owner)

    The relevant question is whether the Modbutton Lite offers a better solution than the legacy SR07 switch. While I like having the Constant On ability on the legacy option, the Modbutton does objectively seem to be a better solution, especially for 18650/18350 powered lights. It’s low profile, bolts solidly down onto your rail, feels more positive to actuate, and seems to handle the higher amperage of modern lights much better than Surefire switches. I would highly recommend the switch, so long as you use the DS00 tailcap for optional Constant On.

  6. Hunter Crumley (verified owner)

    I love the tiny footprint and the amount of railestate the Lite frees up. I recommend pairing it with the DS00 tailcap to give you a constant on option. I’m also happy with the ability for it to keep up with the stronger, newer lights. Kudos to Modlite and BTO for having plenty of these at launch.
