## Discrepancy

EMERGENCY LIGHTS ILLUMINATED IN FLIGHT.  THERE IS A LOT OF HISTORY WITH THE EMERGENCY LIGHTS.  THE EMERGENCY CONTROL PANEL HAS BEEN CHANGED TWICE.  THE EMERGENCY BATTERIES CHANGED ONCE ALONG WITH THE RIGHT HAND BRUSH BLOCK.  THE CAPTAIN REPORTED THAT THE PROP HEAT WAS ON.  MAINTENANCE WILL REPLACE THE LT BRUSH BLOCK.  REMOVED AND REPLACED THE RIGHT HAND BRUSH BLOCK FOR TROUBLESHOOTING IAW 61-10-11, PROP HEAT OPS CHECK WAS GOOD.  CHECKED EMERGENCY LIGHTS IAW 33-51-00, OPS CHECK GOOD.
