as many others, we have the Whelen A500 combined strobe / nav tail light at the tail.
for the second time already over the years, the navlight bulb (part A508-14) has failed. it comes in at a whopping $60+, even without shipping and handling...
anyone found a cheaper alternative? in the end it looks like a glorified halogen bulb with some legs bent sideways... and it's a harsh environment, so the fail will repeat quite regularly.
wanted to avoid replacing the whole unit / going all led right now as the strobe system (from creativair at the time) and wingtip lights are basically fine, including the tail strobe.
thanks for pointers...
