2008-2013 Cadillac CTS Appearance Mods Discussion, CTS-V Headlight Swap in Cadillac CTS Second Generation Forum - 2008-2013; I am just about ready to pull the trigger on buying a pair of CTS-V Headlights with the black housing. ...
Is it correct that the DRL's function through the Low/High Beam light and not the LED box by the turn signals?
they function in the box under the turn signals...which is in the center.
you can search to see if someone did the swap without pulling the fuse..
but other than that its pretty straight forward...b/c the HID ballast is built into the light...there's only one plug to connect the car and the light
