For the pre-LCI e90, I understand that there are 2 brake light bulbs on each side. The owners' manual says that for normal braking only the outboard bulb on each side will light-up brightly, from what I have observed of other e90s that stopped in front of me, the inboard bulb seems to light-up only weakly or not at all (?). But when e-braking, BOTH bulbs are supposed to light-up brightly. Seems like a waste of one good brake light bulb. Anybody ever considered modding so that even during normal braking both bulbs will light-up brightly? This so-called 2-stage approach doesn't seem to have been carried over to the F30 with their LED brake lights, so their must have been a rethink (?)
