Default Tail/parking light fuse keeps blowing

Hey guys, tried searching but could not find anything

The following lights stopped working in my car:
194 bulbs in inner headlights
License bulbs
Tail lights (they still come on 100% when brake pedal depressed)

I replaced the TAIL fuse in driver side floor area pictured here


However it kept blowing fuses the instant I turned the car on, I blew 3 fuses and gave up

I have LEDs in the parking/license bulbs and LED tails, no resistors, but I've had all that stuff for 3+ years without issue until now

What is the next step in diagnosing the problem?

Is there a short somewhere? i read on google to put a stronger fuse in there as a ghetto fix lol, that must be a joke right

EDIT
Fixed it months ago but for anyone who searches this in the future, the problem was my LED tail lights. Had them for many years so i wasn't too disappointed with the failure. The brake functioned fine but the parking light setting was malfunctioning.

Well technically yes it would work, but it is dangerous and if u put a higher amperage fuse in its place it could arc and cause a fire, DON'T DO IT, u gotta short somewhere, I can't recall what else is tied to those fuses off hand, u could have a coin stuck somewhere (yes it happens) in your particular case I doubt it, condensation in your headlight where the bulb goes in would blow the fuse, pull the bulbs and plugs on all the bulbs blowing in that circuit and check for corrosion and moisture underneath where the bulb sits, start easy then go from there... Good luck!

Okay thanks, good idea, I've been driving it in snow and it steams off in my garage every night, not to mention washing it more frequently. So condensation sounds highly probable

check your LEDs... i had this happen to me where there was an internal short inside the LED bulb causing me to pop fuses... i couldn't trace it down until i changed all the bulbs back to stock and it went away...
