I have an automotive electrical problem.
I got aftermarket fog lights that I installed myself. They stopped working simultaneously after maybe 5 months.
-The switch light is still working, and when I press it, the relay clicks (have not tested for continuity).
-The fuse in the fuse box is coming off a pigtail. The fuse is continuous, but I am not sure how to test the pigtail for continuity, or if I have to. I think it's fine since the switch is working.
-Another fuse is coming off the wire connected to the battery in its own case. That is pic related. The fuse is corroded and melted, but it is continuous. Even if that isn't the main problem, it raises concerns about something else wrong with my wiring. Hopefully I didn't short everything out.
-The connection to the battery looks clean.
Can you guys give me some guidance? This is my first electrical project.

the resistance is likely too high when running at the rated current and voltage, replace the melted one

start randomly stabbing for continuity along a lot of your wires. Check for your ground and connection points for corrosion.
Its a fair conclusion that your switch works if it triggers the relay, I would assume the power TO the relay is good, start checking from there.
Also replace that fuse, lol. Usually if you overload a circuit wiring will start to fry/melt rather than the fuse itself. If you put a 25a fuse in a 15a circuit, the fuse would be the strongest part if the circuit. If what the fuse plugs INTO however, is melting, then you got another issue all together.
Is the wiring rated for the amount of power its supplied/drawing?

I bought the wiring, fuse, parts, etc in a package. If it isn't rated for 15A, I'll be really upset with the seller/manufacturer.
I'll go double check the fuse connections, though I didn't notice anything before. After that, I'll head to O'Reilly's for a new fuse.

Start with the easy tasks first.
Fuses and check connections for corrosion. From there start checking for continuity and see if you have bad bulbs (unlikely as fuck since both went out at the same time)
pic, again, unrelated

Replacing the fuse worked! Temporarily at least...there was a little brown on the terminals where the fuse connects, but nothing that looked critical. I'll check it later this week to make sure the new fuse isn't melted.
There was one time I accidentally left them on for 5 hours. Is it possible that caused it?
Anyway, thanks for your help. Here is my car with the lights on.
