Landing light options
My 1976 Cessna 172M uses a PAR 46 size GE4537 lamp for
the landing light (12V, 100W). It is mounted in the lower cowling under the prop and does not last very long. I suppose the vibration of the engine kills the life of the bulb. I sure wished Cessna had designed this landing light installation to allow for replacing the lamp without having to remove the cowling. What a pain to replace a light. I've tried the "rotate it 90 degrees in the holder" trick, but could not tell that this helped any. Many people recommend the Quartz Q4509 as a longer life replacement for the GE 4509 PAR36 size lamp. A best as I can determine, there is no Quartz version of the 4537. If you have seen these, please let me know where. Any other suggestions for a replacement lamp for a GE4537 lamp that might prove to have a longer life? Ronnie |
