I don't think you can buy any H11 LED bulbs - not used in conjunction with load resistors -that won't make the Canbus throw a hissy fit. I bought a set of projector lensed H11 LED's (which are reputed to have as good light output as standard fogs, unlike other LED's, which are just for aesthetics). To go with them I bought a set of 50W 6OHM load resistors complete with H11 connectors, so the whole thing is plug and play, no splicing the wires or anything.

I haven't fitted them yet, Warren, but I know SilkyS3 has.

I also thought about fitting these Philips Diamond Vision bulbs, which I used in my old car and they emit a lovely pure white 5000K light. They will match the Xenons perfectly, don't require resistors and will probably be more effective as fogs than any of the LED's.
