I installed HID lights in my 01 V70. I got the dipped beam failure warning and then followed the instructions to drill a hole in the relay plug. This fixed the warning light but headlights started burning out. I replaced the relay ($5) and replaced the lights and ballasts with 55watt HID lights from vvme.com. I have no error message now and the lights work great. This kit was about $70 with shipping.
