Well, I was there during installation. We know a guy who is a certified master technician (which helps) who came to his garage and installed it there. It took about 40-50min for the install but again this guy is a mastar 12volt technican so no guessing games for him (lucky to know him). The bulbs will not be affected by weather change and are not known to pop or blow, infact if you just replace your bulbs and go with the HID kit its most likely the bulb will pop and leave glass particles in your light housing, you wont have to worry abou this with the HID's.
I feel that its worth it if you want to go for that look, you will end up spending more money replacing regular PIAA bulbs everytime they blow and its clarity is no way near the HID quality.
Put it this way, you wont have to worry about people seeing you at night, they are bright & clear.
