  • When looking for a replacement bulb, the way the socket is wired determines the part number of the replacement bulb. Sockets that are used for a single intensity call for 3156 or 7440 bulbs (single filament), while sockets that have a dual intensity call for 3157 or 7443 bulbs (dual filament). Dual filament bulbs will function properly in a single intensity socket. So a 3157 bulb will work in a 3156 socket and a 7443 will work in a 7440 socket. However, single filament bulbs will not function in a dual intensity socket. CK indicates where the socket's positive and negative terminals are located. CK LED bulbs are very versatile and can be used in any application a CK or non-CK bulb is used.
