horn gap fuse is a protective device which use to protect the equipment from higher voltage.actually horn fuse or horn gap fuse is a thin wire element as compare to load line when a high current drawn in line the wire is melt and line protect.
H.G. Fuse - Horn Gap Fuse D.O.Fuse - Drop Out Fuse
Fusing factor is the ratio of a fuse's minimum fusing current (the smallest current that will cause the fuse to melt) and the nominal rated current (usually the number in Amps marked on the fuse body).
A relay is a switch; it is not usually meant to open under fault conditions (high current), and would likely fail if done so. A fuse is a fault protection device. If a short circuit develops, large currents will flow, and the fuse link will melt, causing the circuit to open. There are also protective relays, which are devices that sense fault, or other undesireable conditions, and are used to send trip commands to breakers.
The resistance of an air gap is effectively infinite until it reaches its arcover threshold voltage; then it drops to near zero as the air in the gap ionizes. It returns to effectively infinite when the current through the gap is insufficient to keep the air ionized.
Usually the type of fuse is encoded into the fuse number. For example a English Electric fuse C20J, the C represents that the fuse is a cartridge type, the 20 is the amperage of the fuse and the J represents the speed of the fuse. Also the J states that the fuse is a type J fuse.

horn Gap fuse, used in 11kV & 33kV circuits to disconnect in case of fault.
The cigarette lighter (I'm assuming that's what you meant) is on a separate fuse than the horn. Check that fuse, if the fuse is fine then your most likely culpret is the actual horn switch in the steering wheel.
the horn is on a fuse with several other systems, it is not on its own fuse. the horn is on a fuse with several other systems, it is not on its own fuse. the horn is on a fuse with several other systems, it is not on its own fuse.

The horn fuse is the same as the stop lamp fuse
Horn Fuse # 14 ( 20 amp) in the fuse panel on the passenger side. Be sure and check fuse. Exchange with another 20 amp fuse and try horn if horn still does not work then it is the horn relay located under the hood fuse panel.
In a 2005 Nissan Sentra, the horn fuse is located in the fuse box under the dashboard on the driver's side. To access it, remove the cover of the fuse box and check the diagram on the inside of the cover for the specific fuse related to the horn, which is typically labeled as "HORN" or "HORN FUSE." If the fuse is blown, replacing it should restore horn functionality.
The fuse for the horn should be on the drivers side underneath the dash. There is a diagram on it that shows the horn fuse.
The 1994 Buick Regal horn fuse is located in the fuse box. The horn fuse will be in the second column, fourth from the top.
The horn fuse works through the cigeret lighter fuse
The horn fuse on a 2002 Jeep Liberty is located in the fuse box under the hood. You can find the fuse box near the battery, and the specific fuse for the horn is typically labeled as "Horn" in the diagram on the cover of the fuse box. If you're having issues with the horn, check this fuse to see if it needs to be replaced.
