I'm getting a HID conversion kit off Ebay. I have a Honda Civic EG and I'm pretty sure the bulb is H4 but I used the bulb sizer from the HID site and they had some other size. What bulb size do I need?
H1/H3/H4/H7/H8/H9/H10/9003/9004/9005/9006/9007/9008/880/881/893/894

My fan doesn’t switch on. I tested the fan and it works, My question is it the sensor on the thermostat housing or the head that turns the fan on??
