I've just taken delivery of a pair of OSRAM Xenarc Night Breaker Laser NextGen D3S +220% Brighter bulbs today - c. £144 on eBay.  

 

However, that may not the complete answer to why the Bi-Xenons in my Yeti aren't a patch on what they were when I bought the car 4 years and 22k miles ago.

 

Do you have Dim Low Beam from your Projector Headlights?

My dipped beam seems more yellow than white, main beam more of a whiter light.

Over time xenon lamps degrade and start to give off a yellowish or pinkish hue. Pot holes and vibrations can take their toll on life span as can using the coming/ leaving home function.

No, I've not yet investigated the state of the reflectors.  I'll do that first. Then, I'll probably try cleaning the projector lenses and fit the bulbs.  If that doesn't offer a significant improvement, I'll need to think what to do about the projector reflectors.

 

You can never have too much light out here in the countryside at night.  I've got some uprated Halogen bulbs to go in as well and I had been thinking about a Lazer light bar.
