1. Uninstall both lower rear taillight housings. Inspect the lens for any separation around the red, reflecting edge of the taillight lens (Figure 2).
Separation will take the form of a red color shade change along the seam. It may look more opaque than the rest of the perimeter.
2. If there is any separation at all, then please replace the complete taillight housing. Keep the good bulbs and any wiring, and only replace the
housing and any burnt out bulbs. Wipe all original, intact bulbs with alcohol prior to install, keeping any foreign matter, grease, oil from
hands, etc. off of the bulbs.
Inspect the bulb holders for corrosion and debris. Repair and clean as necessary.
