The wires are adapters. The actual plastic part that the holder screws in to pops out and you change the whole unit and use the adapters to fit the new LED ones, really simple process. Just need a bit of electrical tape to hold the LED unit in place a bit better as they are quite loose.Yeah I have thought of doing that but I can't seem to find any that look as though they would fit...all the ones on ebay have wires attached but in my holder there is no where to plug in the wires don't suppose you can send me a link to the right ones could you?
Think these ones I bought:
