Sounds like a faulty driver to me… I’d go for a replacement.
It might be a faulty or missing solder connection at the 7135 or pin 5 of the Attiny on the driver board. Or the Vdd Pin of the 7135 or pin 5 of the Attiny is shorted to ground.
Hi, I recently have had problems with my A6 due to a failed spring bypass mod. I purchased a new switch and a new driver and the light will still not turn on. What are the chances I ruined the emitter and is it even possible…?
Thank you
Can you post pictures? Many problems can be identified with them.

here is a picture of the emitter… note that the switch and driver are brand new, I have tested the switch with my other A6 i ended up buying but dont know how I can test the driver.
Let me know if you need more pictures.
Thanks
You can test the emitter with a battery and two wires, if it doesn’t light it’s toast. I’m assuming it worked before. If it does work then it could be a cold joint on the solder pads when you reattached the emitter wires. I’d make sure they were good before testing as the wires cover the pads. The threads on one end of the tube are anodized but not on the other so it’s imperative that the anodized end were the ano has been removed right at the edge of the tube makes contact or you get no light. You might try flipping the tube end for end.
I want to clean up a reflector, how to find the tool for retaining rings in autozone?
The tool is called snap ring pliers.
Don’t worry about autozone. Banggood carries them. 
Got my non-anodized A6 in today, luckily no DOA issues, but some issues none the less.
Lots of aluminum flash/burr needed to be removed from both ends of the main body. It came right off, but caused all sorts of odd issues (flickering/mode jumping) when the light was fresh out of the box.
The only other issue was was some debris in the reflector, but that was easily removed by taking the light down and blowing it out.
Probably a good idea with any budget light to tear it down as much as possible, clean, and reassemble. There’s often bits of loose metal in places that they don’t belong. If the wires are long enough it’s not a bad idea to loosen the driver retainer and blow the hollow of the pill out as well.
I have disassembled the retaining ring but I can’t disassembled more, how can I take the light down?
Check underneath the driver for any other loose bits from manufacturing, maybe wipe it out with a q-tip and reinstall the retaining ring snug but not cranked hard. Also unscrew the bezel and check under the reflector for any loose bits there. Be careful not to touch the reflector surface as it’s easy to scratch and hard to clean without scratching.
If you want to actually remove the driver you need to remove the bezel and desolder the emitter wires then pull the driver out. Why do you want to pull the driver?
I want to clean up the reflector which has some debris inside. I need to unscrew the bezel to remove the reflector? It’s really really tight so hard to unscrew it.
It is recommended to only carefully clean a reflector with compressed air. If you touch the reflective surface with anything the chances are you will ruin it.
Does it unscrew like this?
Yes , like this.
I don’t want to give up, but that is really really tight. Is there any tips to unscrew it?
Latex gloves or a swim cap. Rinse off any talc powder in the gloves to keep them from slipping on your skin. There’s probably metal debris in the threads and it was over tightened. No gloves? Use a piece of bicycle inner tube.
