The location of the headlight fuse for a 2002 Jeep Wrangler is in the
fuse box located under the hood, near the battery. However, it's
not a single fuse dedicated solely to the headlights. The headlights are usually protected by multiple fuses, or by a circuit breaker, possibly in conjunction with other front lighting circuits (like the parking lights).
To find the correct fuse(s), you must consult your owner's manual. The manual will have a diagram of the fuse box showing the exact location and amperage of each fuse, including those related to the headlights. Without the manual, you'll be guessing and could potentially damage your vehicle's electrical system.
