For years, the Fuel headlamp has been a staple in the outdoor lighting industry.With an increased demand for red lighting to preserve night vision, we listened,and the Fred was born. Utilizing the exact same ergonomic and lightweight styling of the Fuel, the Fred enables you to preserve night vision with the substitution of a Red LED for one of the white. The Fred will always turn on in the low mode of the Red LED, so you never have to accidently blind yourself or any other people. To enable the three white LEDs, just hold the button down for 1.5 seconds. FRED.
