I have a set from 69 plate which have only covered 1000 miles, but I will be swapping them back with the genuine LED lights when I get a new van and selling the LED lights instead.
They are not much better than the H4 so I wouldn’t bother if I were you, go straight for the LED, either aftermarket or genuine.
They should only offer LED lights from the factory in my view. This is my fifth Transporter and the H4 or H7 are very poor on a dark rainy night down a country lane considering how big the light units are.
