Do you have anything else wired up to the battery? Stereo, HIDs, etc.

have the charging system checks, could be an early sign of a weakening alternator.

How dim do they get? Every 4cyl Honda I've had has always done this a little bit...

Mine will slightly dim if I turn on the rear window defrost, the AC kicks on, or my stereo is up too loud. It only does it when idling, though. A high output alternator is in the works.

My light dim while i turn on my radiator too. I check the connection and wiring and see like it running fine on 12 volt and 14 volt. Charging system seem to be working well.

some vehicles its normal, but it gets worse when the alternator isn't putting out as many amps anymore.
