find me a driver

I want to build a light using an OEM host from fancy flashlights. I want to use an xp-g emitter preferably. Now for the hard part. I want the light to have high-low and a hidden strobe. What’s the term for this, lock out feature? Also, need it to be compatible with a forward tactical switch. Any ideas?

Which host? FF carries like a dozen different hosts.

My bad. I am going to get the OEM D4.

You could get a Nanjg 101-AK and get the IC reprogrammed.
