2004 chevy trailblazer headlights and dashboard lights would dim and go back on while driving last night. Drove today and did fine? Start of bad Alternator?

That's possible. It could also be a bad headlamp switch or any of the related wiring. You going to have to test the charging voltage during the failure.
