Thanks for all your help.
Now I'm really confused. I just want nice bright lights and don't know which ones.
Halogen, zenon gas? Huh, explain the difference please!
Would you prefer 60% brighter than your standard OEM bulb or 130% brighter is the only question. You pay £10 for 60% brighter Silver star halogen bulbs, for the much brighter Phillips Xtreme bright Xenon you pay £20 (Amazon) to £24 (PowerBulbs) per pair. By the way they are both 55Watt dipped and 60Watt main beam power the same as the Honda OEM bulbs so are road legal and won't burn out your car wiring.
Xenon gas lets the filament burn at a higher temperature so you get more light output and a whiter light from the Xenon bulb.
By the way if you change your own bulbs do not touch the glass part of the bulb, if you do the acid and salt on your skin will attack the special high temperature glass and the bulb will fail withing a few hours. If you touch glass by accident get a paper towel dipped in methylated spirits and wipe the glass carefully and wipe it dry with a clean cotton cloth (clean hankerchief ) or paper towel.
