Light FAQ's

Why does my light blink 3 times?

Your light can blink for a couple reasons

1. Your light needs to be charged. Our heads blink when the battery starts getting low (3 volts).

2. If your light is charged, See troubleshooting Tailcaps and Heads, or reach out to us here.

Can I use CR123 batteries?

You can! As long as you follow these requirements.


  1. Your light head is labeled as a "dual fuel" head. This will be clearly marked under your model number.
  2. You must use CR123 batteries in ONLY 18650 size bodies. In short, due to their limited output, CR123 batteries simply cannot deliver the necessary output on a single cell alone.

Note: when running on CR123 batteries there is a slight output drop when compared to rechargables. For top performance, we recommend running rechargables when possible and using CR123 cells as a backup if needed.

What hardware do I need to mount my light?

Hardware comes with your mount

Hardware, such as screws and bolts for mounting are included with whichever mount you purchase.

The Arisaka mounts we carry, for example, include the screws for attaching your light body to the mount.  

Can I mount my Modlite next to a muzzle device?


Yes! Modlite heads can withstand intense heat and recoil.

Pro Tip: We encourage mounting your light as far forward as you can to decrease "muzzle shadow"

Should I charge my battery when opening my light?

Ideally, yes

It is best practice to fully charge your battery before using your light for the first time.

Note, your first charge will take a little longer than all your subsequent charging sessions.
