Whelen said my completely dead strobes were due to a shorted tube. They walked me threw diagnosis. Sure enough, this strobe tube solved the problem and restored operation! This is one of the least expensive airplane fixes Ive had. A/S had it in stock and I was good to go in a couple days.

Very satisfied with the help from the Lady in sales department ( sorry, don’t remember her name). She went out of her way to help me identify the part I needed. Very happy, RM

Love it. Provides just the amount of spacing I needed.

Beacon bulb works as advertised and Aircraft Spruce made ordering easy and delivery was 2 days early. Thanks again a pleasure doing business with you.

service and company support was 1st class. But come to find out the bulb and the base was defective. so, I had to order another entire beacon assymbly and I went with the LED setup. Any way I can return the A469B bulb?

I purchased the A506-M flash socket as mine had quit working. It arrived fine and was a direct replacement for mine. I moved the tail lamp nav light (the A508) from the old one to the new one. Was easy to replace. Thanks

The position light on our DA 40 was replaced with a cheaper bulb earlier this year and fitting it into the socket was difficult for some reason. It took multiple tries to finally get the bulb to light up. Its just a bulb, right? Well, a few months later the cheaper bulb burned out. So we bit the bullet and bought this one. The bulb went right into the socket, as it should. And it worked the first time. The only reason I didnt give 5 stars was the outrageous price.

The A508 bulb was defective and unusable because the base was too big and it would not fit into the flash unit socket. I returned it.

I ordered two A427 flash tubes for wingtip strobes on my 1975 Cessna 150M. The A&P and an AI worked all day trying to troubleshoot what they did wrong on the installation. After 6 hours they determined both brand new Whelen A427s were defective. Unusual for Whelen. Ive always had good experience with their products in the past.
