...for offroad use only obviously.
I bought some of these: https://www.autobulbsdirect.co.uk/h7-twenty20-projector-led-headlight-bulbs-pair.html from ABD for £70 and couldn't find a guide to confirm which way up was the correct way to run them to get the correct beam pattern. As it's a bit of a faff to remove / reinstall the headlight unit I thought I'd throw this up in case it's of use to anyone else:
1. Wrong way up (although logically I assumed LEDs facing down would make sense) - headlight unit is sat on the table the right way up.
2. Right way up
3. Installed, note there's plenty of room for the fan unit on the back of the 'bulb' and plenty of room to tuck the driver away. Connect the Brown to +ve and Yellow to -ve.
4. Original Halogen beam pattern, I taped markers on the garage door.
5. L/hand LED installed wrong way up. Beam throw is far too high.
6. Both LEDs installed correctly good match to the original pattern (as far as I can tell). Note the elegant way it illuminates the weeds on the drive.
7. 6000k 'white' light, with matching sidelights installed. Very pleased with results. Behind the projector lenses there's no way to tell they're installed.
All working with no CANBUS errors, time will tell how durable they are - not sure about relying on a small fan to keep them cool and not failing under vibrations of driving but we'll see I guess.
EDIT: In lower temperatures these began flickering. I added a set of Philips CanBUS control units (essentially resistors) and they have been working perfectly ever since. There is enough room in the back of the headlight unit to fit all the gubbins without modification.

Total cost for LEDs and resistor kit was >£100 and we’ll worth it in my view.
Has been running fine for 4mths+ now and the car passed its MOT with them fitted.
