What are the regulations regarding lights? Thinking of making a cluster using LEDs, but will i get away with just getting a E marking casted in the
lens? Failing that it will require a set of clusters from a supra etc.
Thanks

Which lights are you referring to?
This si one area where a copy of the manual is highly recommended. It is a worthwhile tool to buy, could save you a lot of grief in the future.
Going to make some up myself, getting a circuit boad made up to mount the leds.
Thanks

Been there & done that - but I went back to conventional lights due to the narrow field of view. LED's are fine when you are directly behind,
but wander a few degrees away and the light quickly fades, especially in daylight.
There are some (slightly better) wider angle leds coming out on the market which *might* improve the vision but I have yet to be impressed.
I would still go for conventional lamps for safety sake.
It is partly for safety I want to go for leds, as it is a pain when they blow, leds should be fit and forget.
The other reason is that they are quite cool looking!
I have thought about the angle, might use wide angle an narrow angle leds for maximium view/ brightness combo.

Like the 24 LED Bulbs on this page:

The theory being they bounce off a standard reflector and 'fill out' the beam.
Might even be cheaper to import some rather than building your own these days.
The ones they have on the buses up here seem pretty bright even from pretty large angles, and they don't seem to use reflectors so I guess they
must use wide angle LEDs. 
Believe me, they are nowhere near bright enough - I had to use three of those 24 led units in each light unit and they were still practically
invisible in daylight
