Was thinking about getting some of these, then handily, one of my headlamp bulbs went! 
So was wondering if anyones tried them, and which ones did you go for?
I bought Xenon Max +100% H4 couple of weeks back. brilliant lights now especially as i fitted new lamp units as well.
one minor problem, i got a few flashes first time out so thought i had adjusted the lights high.
went to local garage, perfect height on both but the guy there said that he also gets flashed accasionally now he has xenon & reckons its because the light is bright white as opposed to old yellow & people dont like them shining at them. 
.
The Ultima is a good bulb.
Very white and very bright!
Have you got them fitted?
I’ve just bought some Osram Night breakers H7 just to replace the standards. I put them in my other chariot and the difference is clear. I just haven’t got round to doing the Mazda yet as I need to go in via the wheel arch I think. Gulp! Anyone on here done this? Is it fairly straightforward?
Headlight bulbs are changed under the bonnet and it’s quite straight forward. Foglight bulbs are changed via the front wheel arch.
I am not 100% sure if it is the Ultima I have fitted but it is one of the better bulbs in the Ring Xenon range. The improvement over standard halogen bulb is quite dramatic.
