JLU Wrangler (JL)

If it were a 2 door it would be called just the JL.  It will have several features that will help you know if you have a JL. On the exterior, is a black air vent right above the front fender. It will also have lights on the front fender, a touchscreen with backup camera, and finally, a push button start.  

Jeep Wrangler JK

If your Jeep Wrangler has four doors, then in just about all cases it is a JKU. 

A few other easy ways to tell if your Jeep is a JK are side facing turn signal lights on the fender flares, as well as signal lights on the grille under the headlights, integrated fog lights into the bumper and performance enhancing features like stability or hill descent controls. In addition, all JK vehicles do have round headlights.

Jeep Wrangler TJ

Jeep TJs also have round headlights, but do not have amber lights on the front grille. Instead, the turn signal lenses are embedded into the front of the fenders. Plus, the factory front bumper does not have integrated fog lights. All TJs are 2 door. Jeep made a longer Jeep with two doors called a L J. It looks the same but stretched out.  If you have one congrats they are rare!

Jeep Wrangler YJ

The easiest, and quickest, way to know if your Wrangler is a YJ is to look at the grille. Wrangler YJs were the first Jeep to offer square headlights instead of the traditional round ones.
