So the Shockwave Lights addon...i uninstalled this small addon and found that default aircraft had various lights missing...all the lights on the Bell Helicopter apart from the nose light were missing including the cockpit light, also the cessnas wing lights were all missing....whats happened?!

I'd probably say you changed the defaults, but for forgot to revert back before unistalling. Check to see if you still have the Shockwave folder in your main FS9 folder. They should be backed up under Flight Simulator 9\ShockwaveLights\Redux_Backup\Aircraft.

Got it sorted, thanks for ya reply tho
