My car tells me the position light bulb has failed, cant find it in the manual.
What and where is the position light?

This is likely one of the bulbs in the rear taillight assemblies. Turn the lights on and look at the rear lights, you should be able to tell which on is burned out. They are tricky to replace, good luck!

We've had to replace the bulb three times. I have a feeling I'm just not getting it in really well. Next time I get the notice I'm not going to replace the bulb and see if it may just need tightening. Not too hard to do if your hands are small and can fit it the well where the assembly is. Rear end lights, just check and see which of the four lights don't come on....
