Stop in for a cup of coffee

Good morning. Nice to catch up on this thread.
What do you guys and gal think of this: driving home last night in my Toyota, a couple times the battery warning light came on AND the dash lights got real bright at the same time, for a couple seconds.

I figure I'll need a new alternator but do you think I'm safe to drive it a few miles tomorrow to the shop I use? Today I'll just ride my bike if I need to go anywhere.

Should I be afraid something will get fried on the 20 min drive, seeing as how the voltage seemed to jump like that?

Were you at any time ever using the rear defrost?
