Default fuse #7

For a while when I use my lights fuse #7 pops.
I have not put in an aftermarket radio. And I have not connected the blue and black wire in the back.
To solve this problem I have replaced the headlight switch for a new one, but this hasn't worked.
What else can I do before bringing it to a mechanic.

First thing would be to remove all lights and remove bulbs all at once see if theres any visable issues . While there all out turn light on again see if it still blows . if not replace one bulb at a time untill it pops thats where your issue lies .

Which lights use this fuse?
Parking, tail, instrumental panel.
Any other?
If I have all bulbs out and it still happens what can be the cause?

There is a tow hitch, but I see no wires comming from.
What about the instrumental panel? If there's a shortage the fuse will pop out if all bulbs are removed.
There is no body damage at the car.

i hadthis problem for a while after eliminating the trailer hitch harness thingy we tore apart the dash and looked at every light. we ended up finding that the cigarette lighter light was shorting on its own ground. somehow got crossed and worn trough. look for that kind of stuff. its not the most fun thing to work through.
