For the 1999 Jeep Wrangler, both the low-beam and high-beam headlights use the same H6024 sealed-beam bulb. The supplied fitment data does not identify a separate projector or non-projector headlight variation, so verify the original headlamp before ordering.
Fog-light fitment may be H3 or H3C. The front turn signals and parking lights use 3157 bulbs, while the front side markers use 168NA. At the rear, the brake and tail lights use 1157R; reverse lights use 1156; and rear turn signals may use 1157 or 198.
Other listed applications include a 921 center stop light, 168 or 917 license-plate bulbs, and a 658 automatic-transmission bulb. Courtesy-light options are 89, 912, or 212-2, so compare the original bulb. Instrument lighting may use 194, 7441, or 2721; compare before replacement.
