I love my HID's. I have had other aftermarket halogen bulbs, and they arent even in the same zone. The HID's are the better option. I to have had an issue here and there with one not firing on the very very rare occasion. But all I do is turn the lights off and on once and it will light. It is worth it for the added light output. I have the DDM tuning 35w 5k HID's in my headlights and fogs. I got the HID's with the highbeams, but to date, I have only used them 1 time. My next set I will just get lows.
