Got the lighted tailcap working in my shortened polished S2+. Itās not blazingly bright, but is quite visible in the dark.
Since I had 8 of the lighted tailcap switches from Banggood, I decided to try resistor modding one by stripping the resistors from one module and stacking them on the other. This resulted in slightly brighter LED output.
- I then took the stripped module and jumpered over where the resistors used to be. This resulted in even brighter output. Since the light still seems to still work even with no resistors on the switch I used the jumpered module as it had the most output.
- I did not install a bleeder resistor on the driver. The driver still seems to be fully functional so perhaps this one doesnāt need it.
- To get the light from the tiny LEDs on the switch module around the edges of the button, I needed to do two things:
- The module rests on an opaque metal washer with just the switch protruding through. I needed to replace this washer with a transparent one. I didnāt have a transparent washer on hand of similar size and thickness, so I cut up a 2x18650 storage box from Mountain Electronics and made that into a washer. Itās mostly transparent and worked well, though I could probably get slightly greater output making a washer from a plastic lens from Flashlightlens.com.
- Surrounding the top of the button, between the button and the housing is a thin ring of hard white plastic. It was opaque enough that the light wasnāt getting through. At first I removed this ring completely. That let the light through, but it was mostly only visible if you looked straight down the top of the plunger. The ring also served a second purpose of keeping the plunger from falling out of the light (unlikely since it actually locks into its rubber gasket) and helps stabilize it from wobbling side-to-side.
- I replaced this plastic ring with a transparent one. I noticed that the bottom of my transparent plastic x-acto knife cover was almost the same size diameter as the white ring. I sawed off the end of the cover then filed it till it was the right size. In installing it, it did split into a c-ring, but that was ok as the break aided in fitting. Itās not needed for waterproofing as the gasket takes care of that. There are grooves at the top of the housing that lock the ring into place. Adding this new ring stabilizes the plunger from wobbling, makes it more secure (canāt fall out even if the gasket fails), and acts as a diffuser making the tailcap light visible from a wider angle.
A note on this mod: If you try it check the rubber gasket surrounding the plunger. I think older metal clicky S2+ hosts used an opaque black rubber gasket. Newer ones use a transparent rubber gasket. This mod requires the transparent one. I noticed that my blue Convoy S2+ host had the black gasket while my green one had the transparent one.
