Surefire KX4

I have an old Surefire G2L-FYL thats just sitting in my FD gear box not being used. Has the KX4 head… Wondering if anybody has a good method of modding this head? I know I could source a Z44 bezel and just run P60 but I have plenty of those and would like to keep the original spirit and vintage of the light with upgraded performance. Options? Also, the Z59 tailcap is still working great but I heard they usually develop problems; any idea what SF is using for warranty replacement on them these days?

I didn’t realize you could use a KX4 with a plastic body: I thought they used the K4(?) aluminum battery tube to handle some of the heat. I would try a search on CPF for this, since lots of users modded this head back in the day, I believe. I never used one myself.

Why bother modifying an old light.
I’ll buy it from you if the price is right.
Cheers.

Surefire doesn’t make that head anymore, so they can’t replace it if you mess it up. There are many replacements heads you can use that will screw right on. Same with the tail switch.
I’d leave it alone, it’s in good shape - I’d buy it too!
