The 2012 RAM 2500 bulb size chart specifies the recommended lamp part numbers and types for all positions of its electrical system, like headlights, fog lights, brake lights, side markers, etc. If you want to upgrade the headlights, the aftermarket bulb you select has to be the exact size your 2012 RAM 2500 requires to fit into the housing and match the wattage and voltage specifications. Pay special attention to the marking and make sure the bulb is “DOT” compliant to avoid legal issues.
