Upgrading 2008 Impreza headlights

Hi - My 2008 2.0l Hatchback Impreza RX has really poor headlights.

Dealership told me that they were "as they should be" (?) So I'm looking to upgrade them. I'd like to put a Lightbar on it, but thats imposible with the body shape.

Been looking at Morimoto XB and they look really good. Sent email and asked if they could confirm the system was UK compliant - this was their reply . . .

All of our XB lights are designed for and tested on US spec vehicles. 
I do not believe they would be UK compliant. 

Can anyone comfirm this to be the case? Or suggest who/where to ask for an official response?

Suggestions for alternative products would be appreciated. Not looking to go off-road nor rallying/racing, just want to be able to see where I'm going. I live in a rural area and most of my driving is on country roads/lanes with no street lighting, and my age is blessing me with less-than-perfect (but legal) eyesight. I just need good bright lights.

Thanks for any input or suggestions . . .

Peter
