No. No repairing. You just throw away.
I think you don’t get it. When the light goes out(I’m talking about a vehicle not your dam house you nitwit) the first thing you do is check to see if the bulb is burned out. If it is, you throw it away and put a new one in.
If you have those damned LED nightmares, you don’t know what the problem is. It could be a faulty circuit board. It could be faulty wiring. It could be anything. You have to get a meter and start testing for voltage here and there. THen, if it is the LED/circuit board thingy, you have to pray there is someone somewhere with one in stock exactly like yours. There’s no standard LED setup. Every light is unique.
LEDs suck. Filament bulbs are the only way to go.
Ah! OK.
