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.

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

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.
