These quick visual cues will help you tell them apart in no time.

Headlight Design Differences

When comparing the 2018 Jeep Wrangler JK and JL models, the headlight design offers one of the quickest ways to tell them apart. The JK features classic round headlights with a straightforward, traditional look and simple halogen bulbs.
