The Trident boasts many useful features; not only 3 switchable LEDs, a dynamic rotary dimmer switch and easily focusable head, it also has a quiet switch, low-battery indicator, beam lock-out function (to prevent accidental activation), and an ‘Active Light Indicator’ on the tail-cap to indicate when the beam is on – perfect for use with the infrared (IR) LED, as a reminder to switch off when not in use.
