Is it Fast an Furious, or Sedate and Compliant?

Ha Ha........ Sedate and Compliant? Nah....... More like "Alive and still kickin'" . The legalities are only half the issue anyway.
Lambretta's don't need this this kind of lighting. There are ways and means to make the headlight work so much better without the need for any radical changes that could attract negative attention and comprimise your insurance credibility.
From a technical standpoint........
A) HID's run very hot...... Not good in the confind space of a scooter headset with all those plastic bits, like wiring and digital speedo's!
B) Most Lammy's haven't got sufficient generator power to sustain this level of electrical demand, especially when tootling around in urban areas.
C) Using a whiter light is not as effective as improving the reflective projection of the available light. Lamm'y headlamps have really poor quality reflectors. That is what needs to be changed..... The quality, not the technology. Fortunately, there are some clever folk out there who can take your headlamp, separate the reflector from the glass, re-silver plate the reflector to a modern high standard and send it back to you with the glass reattached.
D) A halogen "sealed beam" unit would ulimately be the answer.
