Need Electrical Help

[Noah96]

I have a few issues with my truck.
*First off my dome light doesn't work I have replaced the fuse and replaced the bulb with a led one. Visually inspected the wire and don't see and cuts in it.

*Second my cigarette lighter sparks a lot when I try to plug it into the correct place on the fuse box it sparks a lot, Then when I put the cigarette lighter in will kick it out almost instantly.

*And my turn signals dont work, not sure where to start on them.

Any tips or solutions would be appreciated.
