Narrative:
Initially aircraft X had a light assembly anti-collision XXXX installed on the lower. I installed a light assembly anti-collision XXXX new style anti-collision light. The new style is already installed on the top. Technician services says the lights are inter-changeable on an air carrier aircraft. There isn't on eco (engineering change order) for the air carrier aircraft.
