how do u get that light to light up by the cd changer that says ELS? i had a dvd-a disc in there but it didnt light up?

it only changes from red to green while loading new discs....

is this all it is supposed to do or does it light when you have a certain disc or sound set up?

 

If I'm understanding you correctly, that light lets you know when it's OK to stuff in another disc or not. Green means it will accept a disc, red means "wait." It isn't an indicator for anything else, such as disc format, etc.

 

Person above is correct. it only lights up when loading discs
