## Discrepancy

STROBE FLASH BECAME WEAKER AS THE DAYS PASSED UNTIL UNIT WOULD NO LONGER PASS STROBE INTENSITY REQUIREMENTS AND WAS REPLACED IAW A FIELD APPROVED 337BY THE INSTALLATION OF A WHEEL FLASHING LED ANTI COLLISION LIGHT ASSEMBLY AND ADAPTER BRACKET. THESE MONOBLOCK ANTI COLLISION LIGHT ASSY HAVE NOT HAD PREDICTABLE LIFE EXPECTANCIES AND ARE NOT REPAIRABLE.  THEY ARE ALSO THREE TIMES MORE EXPENSIVE THAN THE LED REPLACEMENTS. (K)
