Putting Red LED's In Osram Dot it light



I want to put 16,000 mcd red LEDs in an Osram Dot it light for working
outside when I don't want my night vision affected, the light in
question has 3 white LED's and a resistor (red-yellow-black-gold-
brown) voltage measured from the pins of the LED's is 3.122 VDC. How
would I go about installing these 2.0 volt red LED's? Do I just
change the resistor, if so what value? Unit is powered by 3 AAA
batteries.
