Upgraded Lighting

Has anyone considered upgrading the lighting on their cars? I personally find that I cannot see anything at night!

I started researching online and found many companies selling HID conversion kits which meant that I would have to replaced my sealed beams to H4. Once I did this I would be able to get an "H4 conversion kit." Upon further investigation, I came across www.xenondepot.com (http://www.xenondepot.com).

They sell a product that really peeked my curiousity. What do you guys think:

Apparently this unit is completely street legal and DOT compliant.
