Your manual is telling this:

It is only HIR2 for the mainfrontlights and H11 for the foglights.

With H4 or H7

David23,

welcome to the forum,

but a bit cheeky there IMHO.

Its nice when someone says thanks for your reply.

Why not find the answer by reading about bulbs yourself before asking the question?

(or just look in the 'bulbs book' in Halfords type thing.)

but then there would be no need to ask i suppose.

It's neither H4 or H7 so get your facts right about bulbs LA LA is right it's a HIR 2 but good look finding one.

Yeah I'm with S44GTW on this one.

We're all happy to help, no real need to comment like that.

Anyway, I have changed my bulbs recently. LA LA is right the HIR2 is the fitment, but they are expensive and if I'm right can only be shipped in (when I last looked the states were exporting them)

How I changed mine was to buy a HB4 fitment bulb. The prong configuration on the rear does not fit the slots in the car. I used a file to take off about 5mm from one of the prongs, then it slotted in perfectly. I would suggest that be your best way forward, as HB4 fitments are a lot more readily available, and more reasonable in price.

Hope that helps.

Thanks David23 for your polite answer.

Some words about HIR2 bulbs:

HIR2 bulbs are based on a patent by GE (General Electric) in the year 2000.

The goal (from GE) was to launch a bulb with 75 % candle power of a „"xenon burner“ with a marketprice of 25% of a xenon lamp.

They developed the HIR2 (Halogen Infrared Reflecting).

In comparison with a HB4/9006 lamp (1000 Lumen) the HIR2/9012 has a candle power of 1825 Lumen. The color temperature is 3800 Kelvin vs. 3100 Kelvin. And the lifetime is 800 h vs 1000 hours. (both with 55 watts / 12,8 Volt).

HIR2 has only one filament, there is a reflector for full light (high beam) and low beam. This advantage helps the lifetime of the lamp.

So what is better for iQ??

high priced: HIR2 (9012) by 12 V >>> 1355 Lumen or

cheaper: HB4 (9006) by 12 V >>> only 825 Lumen????
