With some spare time on my hands, I decided I didn't like the LED headlamps on the police car.  They were this off-yellow colour and not really bright.  I picked up some hyper-bright white LED's from Jaycar and replaced them.  Unfortunately the photo cannot do it justice, but they are BRIGHT.  Basically light up area as if they were real headlights!   I may replace the red ones with some brighter ones too.  Just to freshen it up a little.
