With a bit of searching, you can probably find a motion activated switch and wire it into an IR light - if that's what you want.
There are other options, however, that you might want to consider. Just depends on what you want and what will work well for you.
There's a good discussion of IR lights in the baiting section. It may take a while to read through it all, but might be of some help to you.
I have a Gen 1 scope which needs a lot of light compared to your scope, but this sytem works well for me. I'm sure your scope will
see much better than mine with less light.
Will your scope see 940 nm? If so, there are IR lights available on Ebay, DC powered, that operate at that level, and you would be
more covert. Personally, that's what I would like for my Gen 1 scope, but I don't think it will see well at 940 nm. The small lights I have
been using are 850 nm. They do give off a red glow, not strong, but can be seen if you are up close and looking directly into them.
Some coyotes are skiddish at the lights and others not as much.
You might also consider a remote control DC switch to turn your light / lights on and off when you want. You wouldn't need a
motion-activated unit unless that's specifically what you want. I have been using 5 IR lights at my site. Each has 48 LEDs, it's
own photo cell and gives off a lot of light. The reason I have been using 5 lights is for video purposes. For shooting, one light
would be all I would need. They are inexpensive on Ebay.
I use a Driveway Patrol sensor to alert me when something is on the bait. It is DC operated.
The IR lights in the coyote video clip were clustered too close together. I have since
rotated them to spread the illumination to cover a broader area. IR lighting and baiting
has been a work in progress for me over the course of two seasons. I have learned a lot
through trial and errror, and borrowing ideas from others on the forum.
Baiting is not as easy as many think. It's an art form unto itself. I have found it to be
just about as difficult to do as calling. I love calling coyotes, but baiting adds just
one more dimension to it, and in my case, with limited access to huntable land now, baiting
is the best way for me to hunt them.
Here is an example of how IR lights assist a trail camera, which also helps
a video camera with night shot, which also helps a night vision rifle scope.
Here's reading that might be of some help.

Good luck. Keep us posted.
