Anyway, kicked me into action to order the osram hids that have been sat in my basket for months.
Of course, being a fairly modern car, and the hid system designed to be long lasting and tamper proof, you have to take the bumper off to take the lights out to change them.
Looks fairly dramatic

Found the reason why they were both different colours, one Philips brand the other Alite.

Also repaired some of the mounting points on the rear cover with some hot plastic staples. Someone had tried to force it open without undoing the torx screws that hold it on. Unfortunately the left headlight mounting bracket is broken so the bottom of the light isn’t held securely so I’ll have to take it all back off at some point to replace that.
