Headlight goes dim and radio goes off with brake lights

I know this has been posted similarly.
First ride last night. When I got home the headlight would go dim, the radio would go off and the display screen went blank when I hit the brakes.
The battery is about 8 months old on my 02 Gl1800 with 62000 miles.
I got up this morning, the battery had 12.49 volts. I started the bike and had 14.42 volts at battery while idling.. No flashing no radio problems. I'm going to clean battery terminals, I'm thinking the alternator might be weak when hot. Is this possible. I'm going to clean terminals and ride it to see but I won't get a chance to ride it today.

Does it do it only when the engine is idling, or does it happen as well if you hold the engine at say 3500 RPM?

I'm not sure. I went to look into it the next day and everything checked out. Its been miserable weather since so I haven't ridden it yet. > ordered a voltage led and am waiting to get it.
