Switching the RED led to a BLUE led in a logitech optical mouse
Slide this casing straight down through the holes form the old led and then bend until the two pins form the bottom of the casing snap into the circuit board.
***NOTE*** Make sure the LONG wire from the led is in the hole with the "+" sign on it or the led will NOT work
Here's a quick picture of the new led in the casing with the casing bent down into place.
You should STILL have the wire poking out of the back of the circuit board so now is where the second hard part comes. You need to SOLDER these into place. We do not have any pictures of the soldering but make sure there is a nice bead holding the led wires into place so they will not come loose.
