What's the replacement part number for the Octane lightbar incandescent bulbs?

RE: What's the replacement part number for the Octane lightbar incandescent bulbs?
OK, while I'm not ready to declare anything yet (because I need to actually boot an Octane with these installed).  I've just finished changing out two lightbars with these bulbs, the assemblies fit exactly the same back into the white lightbar housing, they are very bright, and take exactly what the bulb specifications claims they would (~220mA for both).

   

   

The bulbs are fragile (I ruined two by accidently installed them upside down on the PCB board..was in a hurry, getting them out ruined both bulbs. So yeah...It's touchy.  Installing the bulbs is MUCH easier if have the rubber bumpers (lifters).  With them them I tried to manually lift the bulbs as I was soldering them to get them away from the board surface and up a little higher, it worked but took 3x the effort.  I may have to get some room-temp clay and create a mold of the OEM one (upside down) to properly position bulbs that don't have they rubber lifters (unmodding a led mod, for example).

   

But it manually lit the assembly with the benchtop PSU @ 5VDC, looked great!  I still believe these are right, but until I run an Octane with them, I'm not going to disclose anything.  Hopefully it won't be too much longer.

   

   

Cheers!

These bulbs are now confirmed! I'm buying up the stock I can on them, now that I've verified they are working fine. Watch the marketplace for details soon.

Yo All,
I present the world's first verified, reverse lightbar mod!  Which I'm told isn't the same as a reverse cowgirl, sorry for any confusion.  Blank

   

The system I bought from Raion had a single LED mod and no rubber lifters (bumpers).  So I had to manually lift them up on the board, not easy...I need to make a jig for this.  The system is now running original-spec incadencents, looking exactly as it did in the 90's!  Beautiful!  See pics, with this I am going to open a marketplace entry for rebuilding or unmodding your lightbar!  Stay tuned!
