I found information for the adapters that plug into the LEAF's wiring harness in place of the original H11 bulbs:
Purchased through Amazon from uxcell. The description is: uxcell 5 Pcs H11 Headlight Bulb Male Wire Socket Adapters. The current price is $9.64 and the item model number/manufacturer part number is: a15040300ux0205
I purchased the JW Speaker fog lights through 4 Wheel Parts (store in Phoenix, AZ). They are also available through many other suppliers that deal with parts and accessories for Jeep Wranglers.
