Rated 5 out of 5 by rlee Works in both standard and CK style sockets, but only in one orientation
I have mine working in a Subaru Impreza, which uses CK style socket. Somehow it works with either of the ground pins shorted to ground. Neat little circuit trick.
The reviewer who gave one star should have flipped the bulb around.

My Subaru has a 7443CK wired socket and this bulb will not work properly and also cause the VDC, ABS, and Hill Start warning lights to illuminate. The marker light will come on, but it will also cause the high mount lamp to glow even when the brakes are not applied. When the brakes are applied the high mount lamp will get brighter but the Philips bulbs will go dark until the brake pedal is released. This is not a flaw in the bulb, this is because Subaru decided to wire its lamp socket differently.
I do hope Philips produces a CK version because the design of this bulb looked far more solid than other products I have tried and the marker light seemed as bright as the incandescent I was trying to replace.
