Bought my 2003 GL1800a recently. It has a green button/light with what looks like a headlight and some straight lines with some squiggly lines on it. Lights up when I turn on the key. It is just to the right of my hazard light switch. My owner's manual doesn't show anything in that position - maybe a blank for adding some accessory. Anyway, if anyone knows what this is, I would appreciate it.
