Hi, I bought both the items, i.e headlights and skid plate from ebay. The lights come with AE. The seller was from Taiwan. It costed me around $600 shipped and arrived with a week and were easy to install. The skid plate costed me around US$290 inclusive of shipment from US and it also took a week to arrive and pretty simple to install.
