Experts: Should I, a newbie, install HID lights?

[iconcat]

First of all, allow me to thank everyone on this board: The info in this neck of the woods has been invaluable, and everyone has been very patient and helpful. Thanks!

Now, on to my question: Should I attempt to install HID lights in my Yaris by following the DIY Manual v.3?

I love the way the brilliant white HID lights look in the Yaris, and I think they'd be especially sharp in my 2007 Nautical Blue sedan. In the DIY manual, it doesn't look too hard, and having accomplished such feats as building a PC from wholesale parts and installing ceramic tiles behind an oven, I think I can pull it off.

However, I've been reading all over this forum, and there are some issues that freak me out a bit:

• Blowing fuses
• Blinding other drivers due to having my lights angled incorrectly
• Electrocuting myself
• Damaging my nice new car in some unforseen way
• Becoming that pathetic mid-30's guy who tweaks his car to regain lost youth

So, what's your opinion? Is it as easy as it looks in the manual? Should it be done at all? If so, do you have advice?

Thanks!
