Multi Coloured Headlights - Help Needed

[Titan-S]

Hi all, Progress is good on the project 4.4 X5 That I posted up a while ago, 2004 Facelift 4.4 Sport Auto

Both bumpers are now painted along with the Hood (Bonnet )

Wheels have had a full refurb along with new rubber all round (Michelin Diamaris). But I need some advice if you please before I post some more pics..

I'm completely confused over the Headlights Side lights (Angel Eyes) one side is dimmer than the other, and they are a distinct yellowish tint as opposed to the bright white I'd like to get.

Dipped beam is super bright white.. Happy with that
Main Beam One light is white (dipped bulb) and the Main is Yellowish too..









So are these a) Halogen, b) Xenon, and c) What are the options to upgrade

I've looked at Hid kits but have no idea what I'm looking at . the kits seem to sell both Dipped , and Main seperately and seem expensive.. And are they just plug and play or is further wiring necessary

Can I get a kit that will make the whole light white

Any help in simplifying this would be appreciated
