Haha no doubt. This kit should require NO cutting or splicing at all, whatsoever.
You really should never need replacement bulbs. Most HID bulbs will outlive the car... they just don't burn out like halogen ones do. There's no filament, etc. Anyway price varies for some of the bulbs but the vast majority of them are about $50 including shipping for a pair. Again though, this is not an expense you will likely have, as the bulbs should last many years.
