I was behind a Subaru XV this morning in the dark and noticed this thing literally has about 25% of the tailight brightness of a normal vehicle . At first I thought it was just one of those ....... 1 out of 100 vehicles on the road that have no working tailights but no ...... it came from the factory like that. Talk about a bad design . The only part of the tailight that lights up is the inch or so next to the clear back up part on the outside of the tailight .
