Please bear with me, I know this topic has been covered before, but, i believe i have found the next best thing to H.I.Ds.
After one of my Phillips Blue Vision bulbs popped, i looked around to see what else was available and saw an advert for super brilliance bulbs at Halfrauds. They dont do these in an HB4 but they do in an HB3.
With a slight bit of modding, you get a 60 watt, extreme white light from your headlights, much better than the Phillips bulbs.
And whats more, these bulbs are on offer at the mo, B.O.G.O.F.
The best mod for the winter, and all for £20.
