Features: Converts your tail light to also function as the turn signal. Adds additional backup lights in old turn signal location (optional). OEM tail light connectors for simple plug-and-play installation. Made in USA. Custom Appearance: This kit will convert the LED tail light on your 2015-2019 Subaru WRX/STi to also function as the turn signal. This kit will instantly customize your vehicle for a much more modern appearance on the road! Additional Backup Lights: Also available with the kit, you can convert the old turn signal socket to an extra backup light. With double the number of backup lights, you will add much more visibility when reversing at night. Each kit is already configured to accomplish this; however, you will need to purchase new white LED bulbs. LEDs must be used, instead of standard bulbs, since you will be drawing power from the backup light circuit. Easy Installation: Using OEM tail light connectors, the kit is 100% plug-and-play and installs in minutes, with no wiring required. The actual installation time is less than 5 minutes per side. You don't even have to remove the tail lights!
