I’m not that impressed with the performance of the headlights but have also noticed that the headlight aim is way out. Says a lot for Network Q’s PDI.

So I was thinking of "uprating" to a Philips xtreme power bulb and then remembered that the headlamp is a single wattage item. The originals are a German made Philips H9(?), H404, rated at 65w. Presumably this an Aussue spec item(?)and illegal for our roads(?), not that this would bother me.

What does H4, H7, H9, etc. actually mean?

If you have not adjusted the headlights try this first.

Well this is purely a guess, but I reckon H is for Halogen, and the various different numbers relate to the fitting type..

If you're looking to upgrade, don't bother fannying about with 'bright' bulbs, just go HID. Get a kit from the states and with the exchange rate, it should work out quite reasonable..

I did the original swap, fitted a pair of 65W H9's into the dipped beam that normally take the H11's, you have to remove a few bits or plastic fron the socket on the loom and trim the bulb plates a little. They where great.

Just fitted 2 sets of HID's lights now, the dipped beam so some proper H11's and the driving lamps, a set of H3's.

Not sure on the H11 HID's, they don't seem as bright as the 65W bulbs I had in before, even worse I think. I am going to swap one back over and see how it looks, back to back. It must be because they are projector lamps or something, not sure yet. But this maybe because the H3's are so bright.

The H3's are ten times as bright, after playing (setting different angles up) with them for a few days I have now set them at the same level as the dipped beam and boy are they bright and don't annoy other drivers, well a little bit.

Money well spend and went for the 6000k sets as they are white and not blue (once warmed up) and you get more light output than the 8000k versions.

They where £100 a set but got some discount as had three sets, 2 for the Car and 1 for the bike.

Ballasts have found nice homes too, the wings where mad for them I think.
