I have 1997 Camry. I don't recall any such light. Are you sure it wasn't the one that shows taillights being out?
I think that light just indicates that a lamp is out somewhere, not specifically a head lamp or tail lamp. Check all your bulbs, including side markers, license plate etc.
I had this as an intermittent problem as well (on my '98 Camry). Eventually, it became non-intermittent. I think that the bulb's filament was partially burnt out but still sometimes making contact. When it finally blew out completely, the indicator light stayed on. Check that out.
