leds: PLCC2 3.5mm x 2.8mm
If changing to blue, white, or green leds you also need one 471 (labeled R157 on the circuit board) and five 331 (labeled R151, R152, R153, R154, R155) resistors. I am NOT sure what happens if you mix blues and reds together, but the same power that will power a blue will blow out a red. Removing these resistors is easier if you use desoldering braid to remove as much solder as you can. Resistors have no polarity.
