Bought from these fine people here -
DRL Headlight Units The bulbs I'd had in my goodies box for a wee while..
No re-alignment necessary providing you get the LED's level across the top. I simply measured up from the ground with a tape & twisted them a little within the chrome whilst they had just two of the four spring clips holding the unit in.
This will level the beam horizontally, and as you've not touched the big adjustment nut of the bowl, headlight vertical alignment doesn't change.
