Make sure the bulb wattage is the same on both sides. The bulb out indicator works by sensing an unbalanced current, usually no flow on one side, and turning on the light. It's just a reed relay inside. If the current is unbalanced due to bulbs with different wattage from side to side or even different maufacturers, the light will turn on even though the lights are on.
