Interesting. As I suspected, there are issues which I am as yet unaware of. The unknown unknowns so to speak.
Some of the cheap LED replacements on offer have extensive finning behind the bulb, which looked unlikely to fit.
Some reviewers spoke about how well or not the centre of the light source matched the incandescent bulb - affects whether the light is focussed correctly into main and dipped beams or dazzles oncoming drivers. Less of an issue as not likely to ride the XS much after dark. But I don't want to annoy drivers either.
The MoT might be a problem for some older vehicles but Miss November is old enough (over 40) to be registered as an historic vehicle. The legal position was changed 2 or 3 years ago - historic vehicles no longer face an annual MoT inspection BUT it is the owner's responsibility to ensure that the vehicle is roadworthy, ie meets all MoT requirements.
Which maybe leaves enough room for a little bit of sensible interpretation.
