Car - 2004 Civic LX Sedan

Anyone know if/where I can get a replacement LED light for my cruise control button and how difficult it is to replace the broken one? I'm assuming the LED light is out since it no longer turns on when I depress the switch and engage cruise control (which still works). This is not the LED light in the instrument panel that comes on when setting a cruise control speed, this is the LED light in the button on the dash on the left of the steering wheel.

Also, I have the stock radio and was wondering if there was a set of RCA inputs in the back of the unit? I was hoping to install a headphone jack-to-RCA connection or something similar so I could attach a couple different MP3 players under the CD-C input (not sure what that is, but I'm assuming a CD Changer/aux input and hoping it doesn't need any sort of pre-amp).

Oh, and how often does everyone else go through wiper blades? I swear - it seems like every six months or less my driver's side blade starts sweating olive oil. It seems like there's nothing I can do keep it clean.
