For Front Amber Park/Turn Bulb
Mentioned above that 3157 is appropriate.
Also that current incandescent 3157 is a screw type bulb, rather than push in.
This item on ebay
or this one which might not be same brightness,notsure
described as 3157, but looks like a push in type.
Will all these push-in 3157 LED bulbs work in 2013 Cmax Energi for Front Turn/Park dual brightness bulb?
Secondly - this bulb
describes the need for a 'Standard' socket as opposed to a CK socket.
Picture at bottom of this URL shows Standard as having grounds on opposite sides of wedge, where 'CK' socket has grounds on same side of wedge.
How can we tell what the current bulb/ socket type is? (Voltmeter I presume worst case?)
Does Ford Cmax have 'Standard' socket or 'CK'?
