Using Your SubiSpeed Tail Lights: To use the tail lights, first make sure they are properly installed. For the turn signals, you can choose between the standard on/off mode and the sequential mode. Just flip the switch in the wiring to change between them. If you want to use the brake light as a turn signal, you can do so as the tail as turn module is compatible. Installation: Most people can finish the installation in under 45 minutes. We've included all the wiring you need. You'll also need to run a power wire from the trunk to the driver's side fuse box inside the cabin for the sequential turn signals to work. Just follow the steps in the installation video with Kevin. Maintenance: Keep the lenses clean. You can use a mild glass cleaner and a soft cloth to wipe them down. Check the wiring periodically to make sure there are no loose connections. If you notice any issues, contact our support team. And remember, these tail lights come with a 2 - year limited manufacturer warranty, so you're covered if anything goes wrong.
