Bi xenon kit questions

Hi all

I've done a quick search and can't find anything for the questions I have..

I'm looking to install bi xenon projectors in my Volvo v60 (2011).

I have seen 2 kits on eBay and I don't know which to buy.




From what I can see one has a relay and the other doesnt, but I'm not sure if the relay is essential or not.

Could someone let me know if they are essential?

I am also debating 35 vs 55w kits.
I had 35w hid kit in my previous car (factory projectors) and found them dull when driving next to cars with factory xenons like bmws etc. So if anyone has some advice for this that would be greatly appreciated too
