If you're handy or know someone who is, you can fab a mount for the light using the snorkel's A pillar mount.
It has become fairly common here in Venezuela. My truck has one, though I'm planning on replacing it with the standard A Pillar brace because I don't see a use for it, therefore there is no light on the light mount. (The shop installed it for free when they installed my snorkel).
Even though its not a Tacoma, here's a (crappy) pic for reference. It was crudely made but I suppose with the light installed you wouldn't notice it. I suppose you could do a better job at it if you wanted it to look nicer.
