Product Description

The SwitchBack S Backup Flashlight Ring enhances your compact flashlight, optimizing ergonomics for searching and shooting. See compatibility chart below.


  • Securely mounts between the tailcap and body of the flashlight.
  • Rigid retention ring helps reliably deploy and index the flashlight from both pockets and pouches.
  • Shoot using a natural two-handed grip (the SwitchBack Technique).
  • Employ all traditional low-light techniques such as Neck Index, Modified FBI, and Harries.
  • Positively retain the light when drawing a firearm, reloading, and malfunction clearing.
  • Designed in collaboration with Chris Costa, and Costa Ludus.

The SwitchBack S Backup comes with two o-rings. See below for compatible lights and recommended o-ring to use.

Notes from Manufacturer:

  • The SwitchBack S Backup is not compatible with lights larger than 0.830 inches (2.1082 cm) in diameter.
  • The E1B- Backup MaxVision comes with a shorter tail cap so this flashlight cannot be activated with the knuckle in the SwitchBack Technique. Instead, users turn the light on with a finger, then can modify the position of the light using the SwitchBack.
