Get rid of the standard turn signal and transform the brake light into one. The high mounted brake light will still let people know that you're stopped and intending to make a turn. It's safe, and it looks good. Another added feature is that you can turn the old turn signal bulb into an additional reverse lights. Paired with our bulbs, you'll have 4 intense bulbs letting everyone know that you're about to back up. Designed for USDM vehicles only. Confirmed incompatible with AUDM vehicles.

Details

This product is neat. With the lack of aftermarket tail lamps on the market for WRXs and STIs in general, you're left with only a few modifications you're able to do to your tail lights.

Get rid of the standard turn signal and transform the brake light into one. The high mounted brake light will still let people know that you're stopped and intending to make a turn. It's safe, and it looks good. Another added feature is that you can turn the old turn signal bulb into an additional reverse lights if you choose to do so. In this setup, you will have to use LED bulbs vs halogen due to the added current draw. Paired with our bulbs, you'll have 4 intense bulbs letting everyone know that you're about to back up.

NOTE: The revised Tail as Turn module now includes a hyperblink fix. No additional hyperblink module purchase is required unless you plan to use LEDs in the front turn signals as well.

This product was designed and fully manufactured by Diode Dynamics, in St. Louis, Missouri. It is fully made in USA.

Optional Items

Reverse Light Upgrade - Light "A" is the original reverse light bulb. Light "B" is the original turn signal bulb. While different in design due to the sockets, both OLM bulbs offer a brilliant, intense, white light.

  1. Great Mod for looks.

    By Neely January 17, 2019

    This is a great mod if you want your car to look advanced. Subaru should've done this from the start. It was a quick 30 min install. I would totally recommend it.

  2. Overall a great mod!

    By Jason October 18, 2018

    I installed this kit on my 2017 WRX. Installation is pretty darn simple. The T-tap connectors can be a bit of a pain, and you can end up cutting a wire if you aren’t careful. So pay attention to that. Otherwise, installation was super easy. One thing I don’t like is the added resistors in the wire harness. Where the wire harness goes, there isn’t a great place for those really large resistors to live, so it makes for a messy install. The resistors are there so you don’t get a hyperblink condition when installing this kit. It would be better to remove those resistors from the kit and simply include a hyperblink module instead, in my opinion. In the end, if you are going to convert the front to LED, you will need it anyway. The only other issue I had was with the LED replacement bulbs for the old back up lights. The replacement bulbs do not fit the socket very well, so they feel pretty loose. I actually had one rattle out of the socket while driving. (I pushed it in really good and hard the second time and so far so good.). Despite the issues, overall I love this mod. So much better looking than factory.

  3. I’m Amazed

    By Tyron October 17, 2018

    I just received it today, installed it and I’m blown away at how much of a difference this makes. I’m definitely happy i purchased this and i can’t wait to get more parts......

  4. Must have mod!!

    By Kyle October 11, 2018

    If you are looking to have a pretty sweet taillight mod, without purchasing new taillights, than this is for you! This is the way Subaru should have made it in the first place. The extra reverse lighting helps out a lot. Especially if you have the smoked taillight vinyl. Very sleek.

  5. Wow they are bright

    By Chad August 3, 2018

    Get the full kit and all LEDs.... I never say I cant see when I put it in reverse.

  6. Highly recommend this product!

    By Francis April 26, 2018

    Install was easy, they look fantastic, and I got the reverse lights upgrade as well as converting my OEM rear turn signals in additional reverse lights. They look amazing, couldn't be happier!

  7. Great with tinted windows.

    By joseph April 21, 2018

    The hyberflash relay is not needed. The product comes with one installed and you will NOT get a hyberblink. I do love this mod. I have a dark tinted rear window and had a hell of a time backing up in the dark until I put in the tail as turn mod. Now with the extra back up light I can see fine. This mod is a MUST if you have tinted windows!

  8. Love the look, wish reverse didn't need tap

    By Nate November 4, 2017

    I love the look even though I personally don't see it often. This plus the fog/brake light really makes the rear lighting pop. Install was really easy, but I wish they made one with a built-in additional reverse light instead of having to tap into itself. It just seems silly if that's ultimately the configuration you want from the beginning. Not that big a deal though.

  9. Must Have!

    By GENESIS July 22, 2017

    These totally changes the look of your tail lights, especially when you Integrate the reverse and turn signals together! no need for a turn signal resistor because it comes with it built in! I really like this mod, and for the price you cant beat it!

  10. Why was this not stock!!

    By Derek May 26, 2017

    Such a great thing to make your wrx/sti. A little different from stock. Install was as simple as changing a light bulb. This was definitely worth a purchase.

  11. Great First Mod

    By Collin March 15, 2017

    I just did this as one of the first mods to my 17 WRX. So simple to install, and the result is a must have. I would highly recommend to anyone who wants a 100% better looking turn signal.

  12. Great mod to improve the rear of your car!

    By Carter February 5, 2017

    Just did this mod to my 2017 STI and the overall quality of the module was great. Installed in around 30 minutes even with the LED bulbs. Very satisfied with the module and bulb upgrade. Would recommend to a friend.
