Aft Position Light (wing)

[Boilermonkey]

Does anyone know the bulb type that is in the WING aft position light?   Figure 33-5 i nthe SM describes it, but I can't find the part number and I don't think it is the standard W1290 that is used in the other part of the wing lights and tail.

I wouldn’t replace the rear white wingtip
lights. If you do, and have LED’s for Nav lights, you’ll find that the gear down light becomes always dimmed (without Nav lights on) and will have to correct that or not be able to see you gear down light in daytime.
I have only had to change one rear wing tip bulb in well over 20 years of ownership. Frankly IMO it’s not worth replacing them with LEDs and then needing to install a relay to correct the always dimmed gear down light.

Something to this but never figured out why. I have LEDs all around so I leave everything on except strobes. Everything is dim but if you know where to install the relay I would love to know the fix.

did the LED lights work for this aft wing lamp?

[Boilermonkey]

Looks like they will, but when I took the cover off the old bulb has a clip with safety wire on it holding the bulb in place and some silicon glue holding the glass cover in place.  Since I had neither silicon glue of thin safety wire I had to abort today.  I'll try again later.

Does anyone know the original halogen bulb wattage or part number?   I replaced with the LEDs that someone suggested, but now get static on the radios.

Some LED lamps have a simple buck/boost circuit that generates a signal.  Especially the cheaper ones.

There is at least one topic around here discussing the possibility that you may need to replace the receptacle when you replace the lamp.

Thanks, I replaced the LED that were recommended on MS, but gave me static on the radios.  Went back to the halogens and everything went back to normal.
