Bulbs have arrived and fitted...
Compareing the standard 9005 with the HIR equivalent. Note the differing shape but the filament is in EXACTLY the same position- no change in the optics of the lights.
The bulbs are 65W as standard.
Rear. The top tab on the HIR must be trimmed down- they arrived with the white paint showing clearly the area to be removed.
A couple of minutes spent with a nail clipper...
Done and ready to install.
All photos taken with fixed settings on my Sony DSC-R1. They are deliberately underexposed...no point showing you apparently bright bleached out images, you won't be able to see any difference between the old and new bulbs...
The best way to view is download all 3 images and switch rapidly between them in an image viewer. There is a very noticable difference.

In practice they are noticably whiter (as you'd expect from the technology which allows the filament to burn hotter) but don't appear artificially coloured or blue (sorry to those looking for something that looks 'cool') but they throw a very noticably larger amount of light on the road, evenly and in a wider beam. Longevity...we shall see.
My particular lights were never that bad to begin with but it's a very good improvement and they are welcome to stay.
The bulbs cost the equivalent of 18GBP each including shipping from the US. Installation requires no more than a couple of minutes with a nail clipper then fitting as normal.
