I'm curious as to what all I might need to build a lumnitop prince with triple emitters and secondaries. If you have any information about drivers, spacers, mcpb's, etc. please feel free to message me or comment here. As with all good mods, I assume this will start at Mtnelectronics.com. If anyone has done this mod, please let me know. Thanks in advance for your help. I'm just trying to get a feel for exactly what I'm facing here.
I don’t own one , so can’t tell you for sure - but certainly it is doable. The aux is the bit that will probably confuse/worry you (it does me lol) also there won’t be masses of room in that prince head. Have you considered one of CRX’s glow disks?
I did my first triple yesterday as it goes lol. I just used a A17DD driver from ali and a kdlitker triple sst20 from kaidomain - you’d need a pill with a hole in the middle though. A normal rear clicky works those.
I have no idea on the internals of a prince, but one would assume your best route (if it fits) would be to use a fw3a if you can get one driver and one of Lexel’s aux boards - or loneoceans has made a new driver with aux support. Both of these, so far as I am aware need an eswitch.
You may also want a copper ‘slug’ or pill to put in there, maybe kiribaru is the place to go for that - or there is a guy in the USA, but I can’t remember his name sadly. User ‘Hoop’ maybe?
Here’s a pill I made to fit - you will perhaps need something similar -
Apparently this is the Prince driver, I had a hard time finding it lol! Hopefully someone else can give you the electronic help you need - that’s where I know nothing really. maybe it could be modded.
You’ll need this driver to run secondary LED’s for a push button light, be aware the secondaries will be part of the UI. (And this driver will not light up the Lexel Aux board LED’s on LOW only High from my experience.)

. With one of these boards from Mtn. Electronics… with the 3 secondary pads. That are not symmetrical.

. 20mm MTN Triple 3030 / OSLON + 3x XQ-E DTP Copper MCPCB
Here is the one using Lexel’s Triple Aux board… the driver wouldn’t light the board up in the Low mode only the High mode… Surefire 6P Defender…
The other 2 Surefire 6P’s using the Mtn. Triple board…
Good luck with the rest….
