These Spyder LED tail lights are easy to install on your 2008 - 2014 Subaru WRX or STI Hatchback. Just follow the standard installation steps for tail lights. When using, remember that adding HID/LED bulbs will void the warranty, so stick with the recommended bulbs. To maintain them, clean the lights regularly with a soft cloth and mild cleaner. This will keep the black smoke color looking great and ensure the lights work properly for a long time.
