I have almost completed fitting LED door handle illumination to 3 of my 4 doors o my VE Calais.
I have done this mod before on my old Falcon, and have been wanting to do this on the Commodore for some time.
Good News, If you have door lamps, then this mod is very easy, and should take you around 1/2 a day to complete.
Bad News, If you dont have door lamps, then you will probably need to run new cable through from the cabin, to the inside of the door, which will add to the time required to complete the mod.
On the plus side, if you choose to do this, then you may as well add a couple of more wires for the Puddle Lamp illumination for the high level mirrors.
I will be posting up a doco for this mod very soon. (I have been taking pictures, and have found this mod to be very very easy)...
