Check the battery and all connections. Sounds like the charging system is fluctuating. Is this problem something new?

Engine rpms can effect alternator output. Less rpms dimmer lites, more rpms, brighter lites or flicker. If you have a digital multimeter you can test, when the problem is ongoing. Goodluck with the car.
