What was found
SCREEN SEPARATED WHICH CAUSES LIGHT TO SHINE THROUGH. THE SEPARATION ALSO CAUSED THE FORMATION OF A SINGLE BUBBLE WHICH DISTORTS ONE OF THE ANNUNICATOR WARNING LIGHTS. AT TIMES, THE BUBBLE WOULD CAUSE THE ILLUSION OF FALSE WARNING LIGHT THAT COULD CAUSE THE PILOT TO REACT TO A FALSE INDICATION. REPLACED WITH NEW UNIT, CORRECTED PROBLEM.
