Precision Switchback RGB C-Lights

Different products for different styles is what SubiSpeed is about. This product starts out as a SubiSpeed exclusive as we desired to provide another option for enthusiasts. No matter what your desired output is, it can be achieved by utilizing these new RGB C-lights.

These parts are for retrofitting the stock LED headlights on your 2018+ WRX Limited / STI. The boards fit well and allow you tons of improved functionality. When mounted behind the stock diffusers, the LEDs produce a much more uniform appearance.

Powered by the Morimoto XBT Controller, you can use your iOS or Android device to dial in almost any color. This new board has an improved diffuser vs earlier models.

They feature two override functions. When you start your vehicle up, they will go to white. No attracting unwanted attention from law enforcement. Connect the controller and you can customize your colors in no time. Also the switchback function interrupts the color you have it set to so that you can use them as amber turn signals.

NOTE: These LED boards MUST be connected to the LED drivers FIRST and then the LED drivers connect to the XBT controller as seen in the last picture. ONLY connect WHITE connectors to WHITE connectors and BLACK connectors to BLACK connectors.

All ground wires must be connected for proper function. Both on the controller and boards.

SubiSpeed RGB C-light Video

This video is a great overview of this brand new product. Please note that the video was created for the 2015-2017 version. Kevin has also made some additional install notes for this product vs the standard Morimoto C-lights.

In conjunction with our original install video, you'll be well informed prior to making your purchase.

New Switchback Function

Kevin showcases the main difference between the original 2015-2017 RGB lights and new 2015-2017 RGB lights. This model is very similar. Hooking up the switchback function is simple and only requires a couple more wires.

Controller Details

BLUETOOTH BENCHMARK: So you just invested $2000 and plenty of your time building a set of completely custom headlights with RGB accent want to control it via bluetooth from your smartphone. Now what? Well, you could either rig up some generic white-box bluetooth controller and download some sketchy app to your iPhone, or you could plug-n-play with the all new XBT controller from Morimoto and control it with their proprietary app that puts the power of control in the palm of your hand!

IPHONE & ANDROID APP: The specialized app works on both iPhone and Android devices. Inside, you've got control over nearly everything! The color-wheel allows you virtually infinite control over the exact hue and intensity of your RGB accessories. Adjustable Fade, Strobe, and pre-programmed color-changing themes provide a handful of special effects to spice it up. If you've got a few favorite combinations, you can save them to your favorites list and load 'em up again later with ease! Watch This Video from our friends at Headlight Revolution that goes over the XBT Controller!

THREE ZONE: The XBT controller is capable of controlling up to three different zones/pairs of RGB accessories. Two pairs of halos and a set of Demon eyes? No problem. Demon eyes, strips, and halos? You bet. You can apply a different color or effect to each zone, or lock them together to easily apply the same settings across the board.

LEGALIZE IT: If you like green, that's great! but it just so happens that white and amber are the only colors that are street-legal inside your headlights. For your safety and convenience - whenever the XBT System powers up (aka whenever you turn your vehicle on) - it defaults the output to white. So when you hop in the car in morning and head off to work - you don't have to worry about pulling up to the parking deck with your headlights still in rave mode because you hadn't had any coffee yet.

PLUG-N-PLAY: Unlike other options out there that require DIY wiring from the user's side, the XBT Controller is 100% Plug-n-Play. There is no wire stripping, cutting, or splicing involved. The outputs are based on an industry-standard JST 4-wire RGB+ setup - making it compatible with most any RGB accessories (not just ones from Morimoto) and it has a 2-pin 9006 male 12V input. Easy!

WHAT A BEAUTY! As if you hadn't already made your decision...the thing just looks plain badass and the quality is apparent from every angle. Pick it up and you'll feel the weight from the potted internals, making it completely waterproof. The combo matte/gloss finish on the injection molded shell is a nice touch, and in true car-guy fashion...we can't argue that the real carbon fiber mounting bracket makes us drool. Mmmm, carbon fiber stuff.

Other available items you can modify while you have your headlight open are the sidemarker covers, HID projectors (with genuine Morimoto parts), and you can also paint the chrome housing another color like flat or gloss black.

The end result can be a truly spectacular, custom set of headlights that function as well as they look.


If you do not have spare butyl sealant in hand, RetroRubber or other butyl sealant is REQUIRED. The OEM sealant cannot be reused! TRS RetroRubber can be stretched to the proper length and width to fit the headlight casing channel. Due to the improved diffuser material and design, you may need to shave the housing down in order to get the OEM diffuser to clip in. This diffuser was modified to increase uniformity and light dispersal.


Profile RGB 80mm Halos for the 2018+ WRX Limited and 2018+ STI

If you want to add more RGB lights, here's a quick way to do it. While your headlight is disassembled, simply add these halo rings around your projector.

Run them on a separate channel for complete control independent of the C-lights. You can also sync them with the C-lights as well.

SubiSpeed Sidemarkers

These sidemarkers are a direct fit replacement for the factory orange sidemarkers that come with 2015+ WRX and STIs.

This is a great modification to perform when you're working on your headlights.
