First of all the mask affixed to the face of your bike looks out of place and ridiculous not to mention gay.
There is a specific light kit from
retro lab if you can afford the price tag.
Alternatively you can DIY but it is a bit of a faff and then there is MOT woes.
When I asked whether or not my bike would pass with DIY'd HIDS I was told 'yes if done right'.
Easiest solution to improve the terrible lights is auxiliary lights i.e spotlights IMO.
Personally I haven't bothered with any of the above and just learned to live with the terrible lights and I ride at night a lot with a light smoke visor.
