2011 TC is ma new Delorean.

Put LEDs on Turn signals (7440 swapped from my '07 I traded for this one)
LEDs on the front Parking lights (194 wedge)
Heck I would've swapped the trailer hitch in the Dealer lot too if it were compatible. Don't think the salesman knew which is why they were quick to tell me they'd install a new one free.
Oh yeah LEDs..... Brake light bulbs. (7443) Gave me all kinds of $#!t.
Blowing fuses left an right. Yes they are the right kind of bulbs. Yes I rotated the bulbs over an over to find the right polarity. Crazy mess is they blew the parking light fuse 1st and worked on the brake light circuit. Then after changing fuses few times, the parking light circuit worked, but hitting the brake pedal blew the brake circuit fuse....... and then my ABS and Trac slip indicators went off .. GRRRRRRR

The indicators went away when I put the reg bulbs in brake sockets.

What gives?

I'm on my phone at the moment, so I can't look it up but there us already a thread here on this very question. I believe it's called bulb sizes. It covers what the problem is and how to fix it.

TC uses 7443 "CK" type sockets, 2 ground contacts on one side and 2 power contacts on the other.
V-Leds.com has a video showing the differences and how to check which type you have.
Just came up against this last night!

ok i know i have 7443 bulbs... What does "CK" mean?
It was my understanding that the difference between 7440 bulbs and 7443 bulbs are the number of circuits. 7440 = one circuit (on/off) 7443 = two circuits (on/brighter/off)..... What am I missing with the whole "CK" thing cause I don't remember the website saying anything about that sorta option.

Maybe should watched the video before asking... lol
LEDlight.com sucks cause they don't even mention such a difference. It seemed so simple.. 7443 base type, check. Color white, check. Time to pay and thats it. They have been giving me the hardest time as I have been trying to find out why they don't work right.

Some vendors don't know the difference between standard and CK, have run into that before!!! At first the video didn't make any sense but after testing with a volt/ohm meter everything clicked.
