To solve your problem with the light out indicator being on you need to replace the new bulb with a stock bulb or equivilent to the 12W 12V bulb you pulled out. The light malfunction system looks at a total wattage of the system and if it there are any deviations it throws the light on. So just replace the new bulb with a new 12W 12V bulb and you should be good to go.
