The couple of LED bulbs I tried on my old 250 were pants at long distance, I think that's why the adverts always show them casting light on something close. I just fitted an LED strip to my ZZR that doesn't cast light but does make the bike vastly more visible from the front (it's under the front fairing and lights up the front from the forks down). If you want more light to actually see with beyond a higher wattage bulb you need to look at HID kits.
Any and all MOT related advice you need is here http://www.motuk.com/Motorcycle%20MOT.asp that's the MOT manual so take it as gospel.
