Ibra Posted September 12 Report Posted September 12 Does anyone know how to get this strobe light for M20J (1987)? or replacement? What is the model and part number? looks like Whelen? Quote
N201MKTurbo Posted September 12 Report Posted September 12 I think it is this one: https://www.aircraftspruce.com/catalog/pnpages/11-03213.php are you sure it is the tube? I would troubleshoot it by swapping it with the other wing tube. 2 Quote

Good point, I will give it a try (only strobe failed not nav lights) I had the impression it’s this one (Whelen A625 for tail/wing), I will double check next time, many thanks ! https://www.knots2u.net/whelen-a625-wing-tip-tail-strobe-assy-part-01-0770058-03/ Edited September 12 by Ibra Quote
PT20J Posted September 12 Report Posted September 12 According to the IPC, it’s either a Whelen A627S or an A610M depending on serial number. The strobe and nav lights are completely separate circuits and the strobe is driven by a power supply in the wing. Sometimes those fail which is why it’s best to verify that it’s the tube. 2 Quote
MikeOH Posted September 12 Report Posted September 12 @PT20J Is there only one strobe power supply, or one for each tube? Quote
KSMooniac Posted September 12 Report Posted September 12 My early J had power supplies in each wing, but I believe later models moved to a single box in the fuselage. Sent from my motorola edge plus 2023 using Tapatalk 2 Quote

If it is bad, you don't need all that. 1 Quote
N201MKTurbo Posted September 12 Report Posted September 12 The tubes normally fail from transferring too much metal from the electrodes to the inside surface of the tube. The tubes turn black. Yours are not black. 3 Quote
PT20J Posted September 12 Report Posted September 12 My ‘94 J has Whelen strobes and there is a power for each strobe (3 total). 1 Quote
Will.iam Posted September 12 Report Posted September 12 When my strobe quit working it was the power supply that had gone out and the price of a new one was damn near the price of an LED strobe and since the left quit after 35 years I’m sure the right was not far behind so got LED for the right side too and that boys and girls is what scope creep is all about. At least i got 5lbs of useful load back those power supplies are bricks of gold by the price of them!!! 3 1 Quote
Lax291 Posted September 13 Report Posted September 13 My 1990 J has a combined Strobe & Nav light fixture on each wing but I'm wondering if the flash tube is the same. First picture is the wingtip and second is the tail. Quote
Pinecone Posted September 14 Report Posted September 14 I have the power packs (three, one for each strobe) off my 86 252 that are available. But 28 volt. Quote
