to give you an idea of what im thinking.

thats a picture of a 1206 SMD LED. they measure around 2mm x 1.5mm, a resistor would be approx the same size, and you solder them together like /\ and then the 2 ends go to the board. altho with an LED. if there is room it would be better to do 2 led's and one resistor, or 2 resistors and 1 LED. such as /-\ or |-| . if there isn't room for 1206's, 0805's might fit. I'd have to experiment to see which produces the brightnest output for the location\lense setup. I'd assume red would output very good through the red lenses.
