Rear running light issues

Good afternoon everyone,
I have a strange dilemma that I haven't quite figured out. Apparently I have no rear running lights at night. My brake lights, turn signals and reverse lights all operate when engaged. But when I'm driving at night, I have no rear lights shining. I changed the fuse under the steering wheel and it immediately blew again. Please help!!!

 

Sounds like there is a break in the wire or something is shorting out in the running light bulb. Pull the rear lights and start from there. Most likely it is a bad connection around the bulb area that is touching metal and popping the fuse.
Good luck, let us know what you find.

 

If it blew immediately, there is a short somewhere. Frayed or pinched wire. I would remove the rear tail lamps and inspect the bulb, and wire individually. making sure nothing is pinched or any corrosion caused by rain water.
