until someone replies, it should reset itself if the proper bulbs are there (either original or new ones with resistors)

another search:

The message will clear itself as soon as you have all the correct wattage bulbs in place. The message clears each time when you shut off the car. If there is still a problem the message will return the next time you turn on the lights.

The message should only occur after you have activated the problem light. Try acivating your lights in stages to find which one triggers the warning, for instance brake lights first then directionals, then running lights, and lastly headlights. This might at least give you an idea where the problem is.

The head light bulb on the link are not led just 2x CAR FRONT LIGHT HEADLIGHT H7 ULTRA XENON WHITE BULBS
The only LEDs are front side lights and they have resistors surely the head lights bulbs would not make it come on ?

and leds even with resistors can be defective. even i have had defective leds for my license plate. sometimes they say they have resistors to make the sale but are either defective or not the right type of resistor

When I replaced the side lights with LEDs the warning did not come on , could it be the h7 s as I just replaced h7 with better h7 or do you think the LEDs are the problem ?

if you put the original non leds in and original h7s do you get error message?
if no error , then proceed only one thing at a time.
