Bit late for that now, these do have fans. I don't recall seeing any in the UK that didn't. I have a hole in my
Headlight case from where I had HID's, perhaps that will aid in ventilation. I also haven't seen an increase
In voltage. I'll see how we go, if i notice the fans have stopped working I'll think about my next step.
Anyway, LED headlights. I think they're fantastic. I had HID's as I normally do with my cars, but I found the output to be really crappy. I've had problems with ballasts and flickering. I found these to be nice and
Bright, the beam pattern appears to be exactly the same as halogen just brighter and further. They are 6.5K temperature so give that pure white with a tint of blue which regardless of what people say i actually like. These were actually easier to fit that standard halogen bulbs because you put the plate that sits under the silver prong in first, then slide the LED through and it twists and locks. If your thinking of going HID I would say don't bother just get some LED's. It's a great compromise.
