if the two resistors in the center are wired in parallel, there is a good chance you can follow bigclives instructions (see link) to dim and basically make it immortal.

You can usually cut off the translucent cover with a knife and twist it off at some point. The PCBs are usually alumin(i)um to dissipate the heat better so it’s very difficult to solder on them. If you can get the bad LED out, bridging the exposed pads or fitting a new LED (mind the polarity!) usually makes the bulbs work for a good while after the repair.

A replacement PCB for LED bulbs that lasts longer and is repairable. You could easily fit socketed through hole components in those bulbs I guess. I’d be all for it.

But that's how a new project idea get to market with the help of @PCBWay 🤣👍

Odd they aren't designed with the LED's wired in series and parallel to extend the life 😕

Should probably be good for a while. It lights up again for now, at least.

(Replacing the LED with a new one would of course have been the proper way to fix it.)

Should be easy to squeeze it back in!
