On my unit those lights are only controlled from the switch by the floor. The remote does not turn them on/off.
I have seen people post that the same lights are controlled by different switches in different units, even though they are the same model and year. Try every switch you can find while someone is watching the lights. I can not even tell mine are on unless it is totally dark. Is it possible you are testing them during daylight hours and not realizing they are turning on?
