Hi beam is H1, dipped is H7.
Best ones are osram nightbreakers or halfords ultra brilliance (my favourite)
They're not really blue but give a nice sharp while light which is excellent for motorway driving.
If you want ones that look blue when unlit there are cheapers ones on eBay with blue tinting to the bulbs that also produce a good white light but allow the blue tint to show when turned off (surprisingly good quality for the price).
Don't worry about blue bulbs causing you to get pulled, it's only if the light from them is actually blue will you incur the wrath of the black rat brigade.
Most blue tinted bulbs merely filter out the part or the spectrum that makes normal bulbs give off that usual yellowy tinted light.
