Changing a 2005 Honda Civic Taillight Lens (aka: removing your bumper)

Step 5 Step Five: The final screw

Now that the bumper is hanging you can get in under the taillight bracket, unscrew that final screw, and pull out the lens.  The bracket the taillight lens is attached to is kind of flexible, and I found it easier to bend it down a little to get the replacement lens in place, then bend it back up. 

There you go.  Hope it all works out for you!
