I tried them in our van amd on the rf. I didn't like them, they didn't spread well and I found them worse on dark back roads than normal bulbs as well being almost impossible to get set right. I switched to a set of osram cool blue h4 lamps and they were perfect.
Everyone loves being blinded at night though right? ?
Passed Finnish MOT, inspecting tehnician wanted to know were I found them, bulb passed light aiming test.
No blidiing to on coming traffic, or distordet light.
