I have checked all my bulbs are they are good, but I still get the warning "bulb of exterior lighting system failed". A BMW mechanic told me it was a voltage issue on my rear lights, but they are all good. I think i got this warning when I changed my headlight. One light is brighter then the other one. Any thoughts?

The intensity of a new Xenon lamp will take time to reach the same as the established one.
