Anyone know what this light bulb is?

[jaylw314]

I have a GPS annunciator lamp for my Garmin 530W that burned out.  The bulb is some weird type I cannot find for sure on the internet.  It has "WT-7046" stamped on the base.  A search for the ID on Google was a fail.

The closest I could find was WAMCO's WL-565-101, which looks right (the second photo).  However, it looks like it actually has "WL-565-101" stamped on the base.  It's also $64 on Skygeek, although I found it at Newark for $10.

Anyone seen this before and can confirm the part numbers?  I'm kind of annoyed that they didn't just use a standard bulb.

Do you have a Garmin manual that legally describes how to replace that light bulb?

No, the Garmin install manual only specifies the pinouts for the annunciator, and leaves it up to the A&P to determine what annunciator to install and how.

So, as it turns out, this is a T1 lamp with a base type called a "Pogo" for obvious reasons.  The WL-7049 is unfortunately a 24V lamp, so at 12V it is too dim.  There is a series of bulbs from WAMCO listed as WL-7041, WL-7043, WL-7049 and WL-565-101 which are either 24v or 5v bulbs.  Some are also made by Chicago Miniature and listed as CM-7049.  It turns out the 7046 bulb is the only 12v bulb, and is used as a flap indicator light on some Mooney's, and listed as WI-7046 (made by Western Instruments).  But for the life of me, I cannot find any suppliers.

I think that means I need to have my A&P replace the light with a different annunciator.  Can I just order one of these and have him replace it?
