V1nny, believe they are H7 and H4.
They are slightly brighter, because they do not have the frosted relecter/lens of the standard headlights. The ligth does appear angled though and although it's good for illuminating signs etc it's not always exactly where you want it. Mine have been adjusted as best as possible. I'd say it illuminates further, but make sure you adjust them well.
my mate who works at mercedes as a mechanic has Halfords super brigh dogs nut bulbs in his beemer and said I should get them for the Clio. He fitted some Mecr ones in mine, they are an improvement over the originals.
I'll pop a pic up later.
Oh take the sidelight bulb out, looks too yellow and no bulb change solves it!
