Assuming you would like installation instructions for the 2016 Honda Accord Custom Tail Lights:
To install, first remove the two screws from the back of the current taillight using a Phillips head screwdriver. Next, disconnect the electrical harness by gently pushing in on the tab and pulling out the connector. With those two components removed, you should be able to pull the taillight away from your car.
Now take your new 2016 Honda Accord Custom Tail Light and connect the electrical harness, making sure it clicks into place. Then line up the holes on the back of the new taillight with the ones on your car, and replace the screws you removed earlier. Be sure not to overtighten them - just snug them down until they're tight.
That's it! You've now successfully installed your new 2016 Honda Accord Custom Tail Lights.
