Heinz, I do not understand this. I am not at all an expert on car lights, but provided the H4 LED bulb have the same geometry and the same light array as conventional H4, why should the reflector have to be different? I agree they could be very bright, but isn't that the purpose? The only way to reduce the brightness should be to make the bulb less powerful, in my mind. In Norway before, a conventional bulb should have no more than 55 W, although 100 W was available but illegal. With xenon and LED this is now changed, there is no limit to the output. Of course the dipping should work well, not to blind an oncoming driver.
