August 5, 201213 yr I tried to change my els lights on a crown vic I had installed to all blue, using the "allbluelights" option. It is basically just an emerglights picture that replaces the default one in the police.wtd file. Once I installed it, my lightbar looks clear and shows no lights. All the other lights (grille lights etc.) are working fine, but the lightbar isn't. What else do I need to do?
