There is a bulb that is out in my instrument cluster. It is the background lighting between the the speedometer and the tach. I have changed this before and it is a push in type bulb. Is the dealer th only place to get this bulb? The local Kragen does not list any bulbs for the instrument cluster but I see there are bulbs that have the same form factor....anyone know of a bulb number that is the same wattage as what is needed by the ML? Thanks.
