The side flashers on the Grand Marshal were re-positioned following a change caused by game update 0.17.1. Also the rear flashers on the Roamer were made a little smaller and more flares were added to the ambulance box for better illumination.
Also, the spots illuminating around the ends of the Grand Marshal light bar are now in the correct position. I've been having a lot of trouble with the other vehicles, so I just left those ones off.
The file has been renamed to (GavrilLEDFlashers.zip), so be sure to remove the old file (ModernPoliceLights.zip).
