well i was a smart boy and did my research, i looked up the T-6 wingtip lights and saw quite a few pics of it with only one light (meaning the second one could quite possibly be an addition) on it, and it was either white or red. i saw very few blue ones.
He's right, that's an odd-ball wingtip to have two, likely a custom addition, however both are of the same size and shape as the single-mounted original would be... my bet would be some insurance/safety requirement had to of been met, so they added the addition and tried their best to make it look original. Had you posted this friday I woulda grabed some pictures for you on Saturday when I was working next to two.
As it happens I have an Osprey Colour Series book on the T6 published in 1991. Lots and lots of pics, not one with a double light fitting. So it seems to be a later modification probably for a strobe.
I came across this on the Banaire website. It would seem to fit the bill. although it says it's for an early type nav light. Which were fitted above and below the wing rather than on the tips.
(Image removed from quote.) There are coupe of warbirds suppliers out there supplying T6 parts. I'm sure you could be up and running in no time.
What colour would you paint the wingtip? Me it would have to Insignia Yellow, the classic T6 colour.
Those look more original, the ones on ours are modern replacements (same general shape and design, but more plastic and acrilic).
are you sure that is from a texan? Ive flown them, but the ones i flew only had one Nav light.
Warbirds for the most part dont have strobes by design. If they do, then that is from the owners own doing.
I am fairly certain, it's extremely similar to two of ours (an SNJ-4 and SNJ-5), I've been cursing and trying to buff out a wicked ding in the paint on one of our two Texan's left wing tip... typical Texan pilot
OK, but seriously, it looks to be from a earlier Texan wingtip, very much like our SNJ-4 or SNJ-5
