[QUOTE=lexus4jess;11222835]2016 -2020 are plug n play. They all have the same wire harness plug. 2013 thru 2015 are not plug n play. Bumpers are not the same. different headlight design from what I see.[/I got a 2018 with the regular headlight and was wondering how to do this and how much it would cost

@mo7517 I'll summarize as fellow members @BMGS and @lexus4jess completed swap and outlined much of the steps/parts needed in their posts. Here are the parts you'll need and the prices from mylparts.com using promo code CL5:

Triple Beam LED Headlamps $2199/each:
81145-30L21 (passenger headlamp)
81185-30L21 (driver headlamp)


Headlamp controllers/ECU's $197.84/each:
81056-30L20 Controller left side, Led, 2016-20, with triple-beam. Led, 2016-18, with triple-beam.

81016-30L20 Controller right side, Led, 2016-20, with triple-beam. Led, 2016-18, with triple-beam.

Techstream programming
1. Go to the Body/Electrical menu
2. Select the AFS module
3. Select the Utilities option
4. First, run the ECU Information Synchronization utility.
5. Second, run the initialization utility.

The total cost for parts is around $4800 brand new from the dealership. That does not include any labor charges to install them (unless you plan to install yourself). You can save some coin buying used headlamps on eBay.

@SalvageGSF from the parts description, it looks like the triple LEDs for 2016+ fit a variety of models listed. See highlighted text in my screenshots below:

Just read through this entire thread, super helpful. I have a related question - what year did the triple beam become available?

Double check my info, but it appears they started offering it when they re freshed the GS which would be in 2016.

From 2016 thru 2020. Base, F-Sport and GSF are all the same fitment. Hybrid too.
