Have an F430 F1 that I want to upgrade its tail lights to LED based. I have read in some places, which I can't seem to find again, that the car measures the power to the tail lights to determine if they are working, which I also understand can effect the F1 transmission operation. Is this true? And if so, anyone have any idea how close the power measurements are? Reason I ask is the LED lights I am looking at would replace the 5W/12W dual filament bulbs with one that use 4W/8W. Any idea if this will cause me any issues? Thanks much.
