I've had one of these. The wiring from the light isn't bad, I believe the two outside are the main beam and the two inside are the high beam.

The problem with them is that their is no facility for a parking light! You don't really think about it but it is apparently an MOT requirment in the UK as it is considered a safety feature.

So, looks good but may not make the MOT. I swapped mine for something else before the MOT was due again.

This was on a streetfighter, not the XTX.
