Mode problem with my BLF A8

Hello, folks. I have one of the BLF special edition Trustfire A8 units from a few years back. The light has developed a problem. The switch usually turns the light on and off, but a partial press does not switch modes any longer.

Is this a known issue with the A8 (or it’s switch or driver)?

Thoughts on troubleshooting?

Thanks!

If you quickly turn it off and then back on, will it turn back on in a different mode? If that’s the case, then it’s just the switch. Good luck sorting that out. That was one of my first lights that met my moonlight needs. If it had more spill, I would have used it all the time. Great light for its time though.

Nope. A quick cycle of the switch makes it come back in the same mode as before. So, looks like the driver board?
