q1 is IS THIS AN EXPORT WH ??? they may be different as I never touched a headlight on one of those.
if not WH then.....
ck is needed for the rear on 07+ and in the middle rear on the early ones.
BUT NEVER ON THE FRONT
you wouldnt use COLOR changing bulbs in rear ??? would you?
front is not CK
its easy to prove with a simple test light and a look at the two types
here is a pic
look at the photo on the right side,it shows both types.
get a simple test light and PROVE it to yourself.
or maybe you WERE trying these in the rear and then YES you need ck but i would just ask WHY/
