Quick Overview

The Rothco G.I. Type D-Cell Anglehead Flashlight is a military-pattern illumination tool used by operators, emergency responders, and field personnel for area lighting, color-filtered map reading, and manual signaling when primary light sources fail.

This flashlight is engineered for durability and long-term operational readiness rather than high-lumen output. It runs on two D-Cell batteries, uses an incandescent bulb for warm diffused light, and features a 3-position switch with a dedicated signal button for Morse and coded transmissions. The anglehead body design allows hands-free deployment via a metal belt clip, and the no-roll profile keeps it stable on flat surfaces during task lighting.

The light filtration system is one of the most tactically significant capabilities of this platform. Four color filters, red, blue, green, and yellow, are stored inside the tail cap compartment and seat directly behind the reflector head lens. Red preserves night vision during map reading, green is wildlife-neutral for field use, blue enhances map contrast and supports fluid tracking, and yellow cuts through fog and reduces glare in low-visibility conditions.

Redundancy is built into the system at every level. A spare incandescent bulb is stored under the contact spring inside the tail cap, ensuring the operator can restore illumination capability without external support. O-rings at both the head and tail cap threads provide moisture resistance, and the high-impact plastic body resists drops and field impacts. This self-contained design makes it a reliable component of emergency kits, vehicle loadouts, and field packs.

Field Application Steps

1. INSTALL BATTERIES: Unscrew the tail cap assembly from the flashlight body, observe the polarity markings inside the battery compartment, and insert 2x D-Cell batteries with the negative terminal facing toward the tail. Re-secure the tail cap until snug to engage the O-ring seal.

2. PERFORM FUNCTION CHECK: Slide the 3-position switch to constant-ON, depress the signal button, confirm illumination from both activations, then return the switch to OFF before proceeding.

3. RETRIEVE AND SELECT FILTER: Unscrew the bottom-most storage cap from the tail cap assembly, remove the filter stack, and select the required filter for your task. Replace unused filters and re-secure the storage cap before proceeding.

4. INSTALL FILTER FOR FILTERED LIGHT OPERATION: Unscrew the main reflector head assembly and place the selected filter onto the clear lens over the bulb. Re-secure the reflector head so the rim holds the filter in place, then activate the unit to project filtered light.

5. TRANSITION TO WHITE LIGHT: Turn the flashlight off when the filtered task is complete. Unscrew the reflector head, remove the filter, stow it in the tail cap compartment, and re-secure the reflector head for standard white light operation.

6. DEPLOY HANDS-FREE: Attach the metal belt clip to a load-bearing chest strap, shoulder strap, or MOLLE/PALS webbing. Activate constant-ON mode to illuminate the path forward while keeping both hands free.

7. REPLACE BULB IN THE FIELD: Unscrew the tail cap and remove the batteries. Remove the contact spring to access the spare bulb stored directly underneath. Unscrew the reflector head, remove the old bulb from the socket, and screw in the new bulb until finger-tight. Do not overtighten. Reassemble the flashlight and perform a full function check.
