I'm doing this thread to help others if they want to change their wingtip strobe bulb. I was under the impression that it was simply a bulb like any other, but boy was I wrong. I had to search quite a bit before I got the info I needed. I'm hoping it's not the power supply, so I went ahead and ordered the bulb from aircraftspruce. For most of us, I believe the assembly is compatible with the whelen 610 bulb. From what I read, you have to switch 2 of the 3 wires. Someone mentioned a molex tool. I went ahead and got one from amazon.
11-03213 WHELEN A610 STROBE TUBE ASSY is the description from aircraft spruce for the bulb.
WHT-2038 MOLEX EXTRACTION TOOL FOR .093 INCH TERMINAL PINS is the amazon description for the tool
I know a lot of people are going toward LED lights, and I may do that if it turns out the power supply is bad. For now, I'm gonna stick with xenon if it's simply the bulb.
Any insight or pointers would be greatly appreciated.
edit---I ended up using a AEROFLASH FLSH TUBE # 73-0270, not the whelen bulb.
