They are not as bright as the DRLs on my E70 when it's on daylight setting. But my E53 has no day setting, and the night setting is about the same brightness as my E70. I realise that my E53 only has two wires to the bulbs, so unless BMW varies the voltage to the bulbs on that pair of wires, only one brightness is possible. Perhaps someone here has crossed that bridge?

Not sure where that weird reflection came from in the middle between the two X5s...
