Headlights from Halogen to Xenon

Hi All,
can anyone tell me how easy or difficult it is to change from Halogen to Xenon and is the difference that noticable.I am sure some of you Landyzoners must have done this,also is it not worth the cost
kind regards to all

Are you talking about Xenon bulbs like Nightbreakers or HIDs

Not sure just want to make mine a little brighter,any info would help

Xenon bulbs are a straight replacement for halogen bulbs and are certainly an improvement though some say they don't last as well.

HIDs are a bit of a grey area legally if your headlights aren't self-leveling (I've no idea if D3s are or not) and aren't a straight replacement but plenty of folk have done it so I can't imagine it's that tricky........though if you blind me you might find a Series ambulance coming through your windscreen which probably isn't ideal
