I had that same burned out bulb indicator. It turns out that there was a production problem with some of the driver side tail lamp assemblies. One of the bulb sockets was not coated properly during manufacturing and it tends to corrode causing the failure. Its kind of hard to notice that the bulb is out because there are two bulbs at the top of the taillight and only one is out.

I replaced the bulb twice and it worked each time for a couple of months before the indicator came back on. I finally took it to the dealer and they replaced the socket. No problems since.
