I'd suggest spending a little more and getting ones that you know will work, otherwise you'll be messing with returning etc.
Also i'd recommend 4300k or 6000k. 8000k will be more blue and therefore less light output and also more likely to be in trouble with plod.
there's a 99.9% chance the £55 ones will bring up an error if you turn your lights on whilst driving, as regards to colour on standard halogens it seems anything over 4500k is illegal / non e marked
+1 that you should spend a little extra and get some that will be guaranteed to work!
I spent a good two months going backwards and forwards to the
shop with sets of HID ballasts that my car simply didn't agree with! (Inclusive of "Canbus Pro").
I finally bought the "Terminator" kit from HIDs Direct (
linky) and they work perfect, first time, every time, with no errors and no hassle!
8000k for me is asking to be pulled over, as they're noticeably blue. 4300k for me is a bit yellowy, so I went for 6000k and have never looked back!
You have to think about what YOU want from them though in terms of colour, and go for it!
Hope this helps
