Are you certain that your vehicle is designed for CK applications though?
FOR REAR TAILIGHTS on the GRand Cherokee WK: 07+
when they changed to 1 bulb for park/blink/brake they went to the CK sockets.
so thats any Grand Cherokee 07+ need the CK LED bulbs.
Also, to make any led work on the circuit we add a 6 ohm resistor.
FRONT TURNS on a Grand Cherokee: 07+;
ARE NOT CK and any of the 3157s will work. and need a 3 ohm resistor due to more than one light on the circuit.
So Steve: Will you let Putco KNOW that their website is WRONG and that I would be HAPPY to be a tester for the CK bulbs if they make them
NOTE to others: standard bulbs fit both sockets due to way they are wired. LED is more specific.
