I installed them in fog lights H3 in Passat b5.5
due to the projector mechanism, the light beam is only reflected downwards on the road surface, so it does not blind other drivers.
With reservation, I installed the 100w ones because there are reports from various forums about melting of the reflectors and wiring... after using them more than once for over an hour each time, I did not encounter any problems.
Regarding the lighting issue, I did see a difference, but it still wasn't exactly what I needed, so I'm going to switch the high beam lights to Osram H7 NB Unlimited.
In summary, the bulbs are good for fog lights, they don't create any problems, the performance is satisfactory, now the lifespan and whether there will be any issues, only time will tell.
