    First check your batter connections at both ends, clean and tight. Check the inside of the light socket to make sure the connections are free of crud. I don't know how you checked the bulb, but I would try a new one once you're sure everything is clean and tight.

    If they are getting brighter. You may check the voltage at the battery while running. To see what the voltage regulator is putting out.

    Does the stop light work with either lever, or just not work at all? Lights getting brighter can be a sign of a marginal battery or regulator.
