Reply to Replacing VCI-100's LEDs

Was out of action for only 1 month before I noticed that my VCI-100's Effect buttons' LED had gone on vacation, most probably permanently so I mapped them to the Cue ones. Previously, the cues for Decks A & B in Traktor were mapped to the left and right Effect buttons and Decks C & D mapped to the two Cue buttons.

Does anyone know what's the value of the little LEDs inside and how much work is needed to replace them on my own? I've opened up the casing a few times and done the arcade button modification myself but didn't take a look at the other bits.

ps. Sorry if this has been discussed before but I've been missing a long time and replacing VCI-100 LEDs didn't turn up in the search.
