I was of a similar mind on getting rid of it too....until I nearly got rear-ended by a #@%^&* a**hole in a pickup while I was slowing down, signal flashing, to make a right turn off the highway. Also, I hung the old lightbulb & socket, still connected in the trunk, while I waited for a replacement so it wouldn't muck up the bulb-out indicator. If totally removed, I'd probably solder in a small resistor to fake it out.
