That's the bulb failure warning, it monitors the headlamps, tail lights,
and brake lights by comparing the current draw between the two sides. It
is prone to false triggers due to dirty sockets, mismatched bulbs, or
loose/corroded connections.

I should also mention that if you ever find that a light just won't work
no matter what you do, the sensor is probably the problem. I've seen it
twice, taillight on one side wouldn't work, turned out to be a cracked
solder joint inside the sensor which is under the instrument cluster on
a 240 and in the fuse/relay panel of a 740.
