How it's like this, you this rarely mounted in the dark and the first night journey was slow in coming (1,5 weeks).
Here, however, I turned directly to the first few meters an extremely short beam range determined (compared to the 4 transition bulbs at the discount).
In meters it was just ~ 20m (less than half the Leitpfostenabstand on the highway).
From experience of Osram, I knew that something happens time and usually the contact to the manufacturer is the fastest solution to the problem.
So bulbs again exchanged by the discounter and reported to the workmanship of the Bosch Customer Service.
After 3 weeks (!!!) was also finally a response from the Customer Service:
"May we ask why you have this Glüphlampen (original text) reclaims not immediately of Amazon?"
....
No solutions, no apology for the inconvenience ...
The lamps went straight on it in the bin and this outrageous Email I have not even responded.
For me, these were the last Bosch bulbs because there is apparently saved to quality control and service!
