Yes that is TimMc, place a 1mm thick washer around the emitter just over the MCPCB, and use it as a slicing guide. You remove most of the dome, but still leave a protective layer on the led. It should sort of look like an XP-L HI emitter.
Available @ Simon’s Ali store
Actually, I don’t see any point in S21A since S21B became available - it beats S21A in both looks and functionality.
Purchase is not obligatory. Buy what you like. But you would be surprised how well old models sell.
Clear switch cap would be better imo.
I'd say “just different”.
Rubber cap allows installation of a lighted tailcap.
Hello Simon,
Since I modded my Z1 with a 4 LEDs 10W IR emitter … so now I’d like to “know” when it lighten up or turned off (without looking directly at the LEDs which emit a dim red when ON) : could it be possible to get a lighted switch that would fit the Z1?
thank you
Had to goggle the light to see a pic of the switch. Looks like the SS switch that comes on the colored-body S2+es.
There’s a translucent ring around the button that can leak out some light, so while it wouldn’t be bright, you could swap in a lighted-switch board underneath for a perfectly usable indicator ring.
Or drill out and rethread the hole to use the blue-lit rubber-capped switch (on the Convoy website).
Point being, don’t think there’s a lit SS switch that’d be a drop-in fit.
I could swear i saw SS switches with lighted transcent plastic around the switch...
I hope somebody can confirm and add some info as well
The metal switches have a bit of transparent plastic around them, but it requires a lot more light to shine through.
This is what am talking about.
And that guy has lighted SS switches in every Convoy 0_0
Umm, like I said… 
Can someone explain the difference between the S21A and S21B?
Sorry if am asking again but English is not my first language...so about what part you were talking about exactly?
SS tailswitch, like on colored S2+es.
That seems to have extra plastic around it though. Not a standard S2+ switch…
Ok, lol, that i am aware of. Have it here...
Guy in video have some kind of a plastic around the SS switch that shows some light which my S2+ doesn’t have...
And i’m still confused with your answer.
Exactly. Thx oweban for pointing it out
Point being, might be possible to undo any retaining ring, swap the switch-board for a lit switch-board if it fits (might need a washer or something if not), and let the light leak through.
What’s the difference between the s21a and S21b?
