You have a blown tailight bulb causing a short, of if it's like my 95 Bronco somewhere between the engine bay and the tail light (yes it's a PITA) a wire is grounding out to the frame.

"on 02 explorer its for tail lights i used 15a like manual calls for its just not working i even tried a 20 amp fuse"
Not trying to sound like Dudley Do-right here, but using a bigger fuse than called for, even for a little while, is not a good thing to do. The wiring and electronic components in a circuit protected by a fuse are usually rated for the amperage at or just slightly above the amperage rating of the fuse that is protecting them from getting fried. Increasing the fuse size could allow more current than is safe to flow through the circuit and then a short in one component could draw enough current to fry other components and even fry the very wires in the circuit. It could even cause a fire. Think of it this way, the cheap replaceable fuse is the weak link that will blow first when amperage is exceeded(short circuit) in a circuit. By doing this, the fuse protects the entire circuit from overload. If you put a larger fuse in a circuit than called for, then the components and wiring in the circuit become the ‘weak link’. But they are MUCH more expensive and harder to replace than a simple fuse. I was installing a stereo in my car once many years ago and while connecting wires I got something crossed to hot and ground when it should not have been. In about a microsecond and before I could react , the plastic insulation melted off the wire and it turned glowing red hot. Lessoned learned for me, be very careful and cautious when messing with the electrical circuits in vehicles.
