I'm no expert on the WK. Hopefully someone more knowledgable than me ill chime in. But, going to the V-leds website you can find out what type of bulb the cargo area uses. There link takes you to a Sylvania website where you can identify any bulb you have. Then when you get the number of the bulb you want to replace, like 579 for the cargo area, simply type in 579 in v-leds search box. All the bulbs that show will work. Some are more plug and play then others it appears. You'll have to decide which color and temperature you want to go with.

 

194 will also work, and you'll have a larger selection. For the lift gate bulb, Look for a "forward style" http://www.v-leds.com/194-168-158-LED/5K-White-LED/Forward-Style/tc511426-1-2//page/1/checkForLanding/true
