In the Wrangler's case, the decision to develop an LED for a single model year of the JK before its replacement arrives – or two if you count the extended run of the current model alongside the new one – might seem strange, but we aren't complaining. The current headlights are one retro cue that sorely needed eradicating, plus this almost guarantees LEDs for the next-gen model. Any 2017 Wrangler can be equipped with the new LED headlights and fog lights – the LED lighting group will be optional on the Sport and Sport S, and standard on Sahara and Rubicon.
The Cherokee is a slightly different story – HID headlights are currently optional on that model's Limited and High Altitude trims and standard on the range-topping Overland. Next year, the brighter, more focused lamps will be standard on everything but the base Sport model, where they'll be optional. For the wee Renegade, meanwhile, HIDs are a "late availability" option as part of the safety and security group on Latitude, Limited, and Trailhawk trim levels. If you want a 2017 Renegade Sport with the better lights, though, you're out of luck.
Jeep hasn't announced pricing for its 2017 offerings, so we don't know what sort of premium the LED and HID headlamps will add. We just know that whatever the price, it will be worth it. And you can bet each unit will have some sort of Easter egg Jeep design detail on it.
