WTB/LFI: Xenon HIDs

[scene]

I don't know the specifics but I just know they have characteristics of intense bright blue lights. I want the most brightest yet legal version of these types of headlights. I often have to drive late at night (4-5 AM) and the extra visibility would help to keep me awake and to possibly reduce any "surprises" that I might encounter.

I do not care about the price and is it possible to install these headlights without any experience in DIY work on a car or do I have to bring these to a licensed mechanic or shop? ALSO, if you can give me a list of options that are available for the 2010 Toyota Yaris, that would be great. I obviously had no luck going to local shops here and the employees often gave me a confounded look or perplexed stare when I asked about "Xenon type headlights," for a lack of better words.
