Still working on my Starduster, after installing the belly sheet metal found the strobe not working. It's a Whelen unit, that I think the strobe tube is bad. So what to do, buy a $150.00 strobe tube and hope that's it or look at something else. Looking through the internet I found a company called Kuntzleman Electronics, they have single strobe (power pack, strobe tube, lens and wire) for around $165.00 delivered, I bought one. The size of the power pack is about the same size as the Whelen unit, but weighed over 1.5 pounds less. The strobe light assembly was just a few ounces. install was straight forward, except I used different fasteners then what was provided (they provided stainless self tapping screws) I used #6 machine screws, and soldered and shrink tubed the connections instead of using the provided butt connectors. It's in and flashing, I saved some weight and maybe some money. If you are looking at installing a strobe you may want to look at what these folks sell. They also sell a wing tip running light / strobe unit. There Phone # is (610) 326 9068
