One more thought about five pairs of HID auxiliary lights. These are not like LED lights -- HIDs use a lot of amps, and adding ten HID lamps (in addition to your headlights and taillights) may be a little too much load on your charging system, especially as you sit at idle (at traffic lights, etc.). Then, adding A/C (the compressor's clutch, that is), and maybe rear defogger, on a rainy evening (when you're most apt to want fog lights), and you'd better watch the voltmeter you've installed (you have installed one, haven't you? :-)

Have fun.
