Sorry, but the inverter uses 12v DC to turn it into 120v AC. The converter is the one that uses 120v AC to turn it into 12v DC and supplies power to the lights (along with the battery). They are kinda named really close and you're not the first to confuse the two.
What I was trying to say previously is that a bad inverter (12 to 120) can sometimes cause a AC ripple to be on the 12v DC input side. A properly operating inverter would not do this but a failed one might.
Measuring the battery voltage going the the inverter with a voltmeter on the AC setting would be able to measure any "ripple" coming from the inverter and give the OP an idea if his inverter is bad.
