Just picked up a beautiful 2010 V8V last week.
Passenger side turn signal is out, so I'm going to take it out this week and get the circuit board checked.
I just noticed that there is quite a large gap between the headlight and bodywork on that side (see pics).
I've read that the mounts are prone to cracking/breaking.
Anything I should check once I take the light out?

 

The front mounting is aluminum and is adjustable, so when you remove the headlamp you should understand how it works for alignment to the body panel. Hopefully you can get the lamp board repaired. There is several threads about it if you search.
