I now need to change my 1st Set Bosch +90 after 19 months and 65Tkm (frequent travelers with steady light). I think that's a really good value, the Night Breaker came earlier because not begin to ran. The illumination is definitely the best that I have achieved so far in this vehicle (BMW E46).
The new rate will be somewhat brighter than consumed, but what I see as normal.
Price / Performance I find in this product appropriate in any case.
