LED bed lights blew fuse

I noticed my bed light wires came apart. I tried to solder the connections using new wires(18g) to extend the length. Every time I turn off the lights on they blow a fuse.

looks like the Lights use 18g wires and the switch uses a larger gauge.

I soldered the positive from the lights to the switch and soldered those two into one wire going into the positive fuse block. same method for the negative.

Am I doing something wrong? The fuse block is connected to the battery using 10g wires.

 

Definitely need some details on the lights being used and pictures of the setup after the repair

 

I’m dumb hahah I kept wiring the ground and that’s why it kept blowing a fuse.
