Hello! 

Up for your consideration is this color-changing LED headlight kit. This will work with all 2011-2015 Kia Optima LXs that use H11 or H11B headlights. These were purchased for my 2013 Kia Optima LX and were removed when I sold the vehicle. They were installed for less than ten months. They were purchased from the K5 Optima Store (online, see photos where it lists that store's info). You can still find them at that store, too (new cost is $159.95). 

My vehicle used H11B bulbs, so what this kit includes is the H11 attachment, and then a separate adapter for the H11B sockets. That's why these could work in either type of fitment (H11 or H11B).

The only edit I made was, on the orange washer, some of the material was cut off so it could fit properly. Not sure why mine didn't fit without the cuts, but it didn't. Everything still works as intended.

Please see below for some of the information from the K5 Optima Store regarding these lights.

"These brand NEW high powered COB LED headlight low beam & fog light kits with built-in color changing RGB LED Demon Eyes, are designed to outperform your existing halogen headlight light bulbs. These feature the new groundbreaking color changing RGB LED technology, which allows you to have complete control over the color of the demon eyes built into the LED bulbs themselves, using your smartphone or tablet and the free app in the app store. The separate bright white light LED is a tremendous upgrade over the stock incandescent bulbs for either your low beams. Each COB LED bulb emits 6,000 lumens using COB's latest technology. These new LED bulbs match some of the top of the line HID bulbs out there on the market. 

These kits are rated at an IP67 Waterproof rating, & are also dust-proof & shockproof, removing the hassle of changing bulbs due to shattering.

• This headlight portion of this kit is 100% plug & play, and requires no splicing of wiring, running of relays, or any other modifications to complete the installation. The only wire that is run is to power the LED RGB color changing demon eyes feature, which consists of a single power wire that you connect to power on the vehicle, and single ground wire that you connect to the chassis
  
  
• This kit is designed specifically for customers wanting brighter light output, without having to modify or wire in, say, for example, an HID conversion kit."

Please note, there is no warranty that comes with these, but you can check my feedback (100% positive) to bid with confidence. What you see in the pictures is what you get. All elements work as they should. These were bought new, then used in my personal vehicle, then removed before the vehicle sold. The price point/discount from the new price at the K5 Optima Store takes into account the used/slightly modified factor.
