Get rid of orange indicators and clear out rear lights for that fresh look ;)
       
 Clear Lights
 
Difficulty - *

These bright pinky Citroen C2 clusters would look much better clear.. It's all down to personal preference, but I'd stick to only clearing lights on silver cars only as it tends to suit them very well.  
Right... Go VERY closely around the edges of the lights with the polygon lasso tool.  

Go to - Image>Adjust>Channel Mixer and click the Monochrome tick box and then click "ok".  
The light will then have successfully turned clear, don't forget to repeat this for the other side too, or you'll have odd lights heh.
