Have the H4 bulbs built into a 5 year old Hyundai i10, as this felt operate the factory with candlelight value. The installation and removal was a disaster and I had to take the help of the Hyundai dealer. Both headlights had to be completely removed and the car for this purpose on the .Bühne. Since my dealer had known this and I'm good customer there, the exchange was carried out for free. Of course with the design of the car and nothing to do with the pears. In darkness and rain very good light with little to no glare. But does not come close to the xenon my i40. For durability, I can not comment because the i10 has now been sold
