you've got a short. probably best to take it to a garage unless you're experienced at checking and changing wires.
Try looking at your tail light socket if it is fried that will blow the fuse
had similar problem ended up being pigtail for my trailer lights had a bad connector and a spot where insulation rubbed off creating a short and blowing that fuse
Circuit overloaded, short in wiring, or the fuse you are using is not the OEM correct fuse.

If the fuse keeps blowing, there is a short somewhere. Since the dash and tail lights both go through the headlight switch, I would check the wires from the switch connection all the way to the tail lights, and the dash lights. Somewhere, a wire is crushed to ground or something like that. Make sure your switch is property connected and is a good switch! Good luck!
To replace the tail lights on a Lincoln Mark VIII, you typically need a 15-amp fuse. However, it's always best to consult the vehicle's owner's manual or the fuse box diagram for the specific fuse location and size, as variations may occur depending on the model year. If the fuse keeps blowing, it may indicate an underlying electrical issue that should be addressed.
Yes, on many cars the dash lights and the tailights are fused together. If it keeps blowing fuses, you may have a corroded tailight bulb. I hope this helps you. Mark could possibly be the headlight switch as well
Have to first remove all the light bulbs, then put in a fresh fuse, if it still blows, then you will have to follow all the wires to find the short. If the fuse does not blow, then the problem is with either the bulb or the socket.
A corroded ground wire will cause a fuse to blow. Until the ground wire is cleaned the problem will persist.
