Diode Dynamics Tail as Turn Module


In Stock

Upgrade your Existing Reverse Bulb to LED

Add a second reverse to your light set up in existing turn signal location.


NOTICE: Compatible with USDM models only / 3M Adhessive tape not included

This kit will make your LED tail light also function as the turn signal on your 2015 Subaru WRX or STi. By eliminating the factory incandescent turn signal bulb, and instead operating it through your LED tail light, you will gain a much more modern appearance.

Using OEM plug-and-play tail light connectors, the base kit is 100% plug-and-play, with no wiring required. You don’t even have to remove your tail lights!

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

This product is designed to be used with Diode Dynamics products. Use of non Diode Dynamics products may result in improper function.

Please note: For ease of installation, load resistors will be integrated into each module. This means you will not have to tap any factory wiring to eliminate hyperblinking, or change your flasher relay. If you do already have an LED flasher relay, you may continue using it with this product.

If you wish, you can also convert the old turn signal socket to an extra high-mounted backup light! Each kit comes with the wires to accomplish this (see video for details) but you will need new white LED bulbs. You must use LEDs, not standard bulbs, because you will be drawing power from the backup light circuit.


This is just the module.  You can upgrade your back lights to LED as well as add an additional LED bulb where the factor turn signal was.

Factory Reverse Light: 921

Factory Turn Signal Bulb: 7440
