Hmmm Gas Discharge Bulbs


I need to replace a dipped bulb on my GT, but am getting confused by Halfords website - They're offering With or Without "Gas Discharge" bulbs.

I know I'm after a 55W H7 bulb and I thought that would be enough

What's the difference and what should I go for? Or is there a better place to shop for replacement bulbs?



p.s. It looks like the Dipped and Main Beam bulbs are interchangeable - is that true (quick fix)?

Re: Gas Discharge Bulbs

"Gas Discharge" = HID.

If you don't have HID then you just need an H7

I thought the main beams were H1.

Re: Gas Discharge Bulbs

Never trust the Halford parts guides ... most of them are wrong when it comes to the 156 (and probably most Alfa's!) .. although most simply say "Ask at Spares Desk" ....

H7 dipped, H1 Main and Fogs
