You can get the Bentley manual here: https://www.amazon.com/s?k=bentley+e...ref=nb_sb_noss
Tail lights - Assuming you've checked the fuses, twist them out and clean the contacts on the bulb holder and lens assembly. I usually rough up both areas with some fine sandpaper. You might want to bend the contact tab down a little bit. Positive ground if memory serves. You can get moisture in either assembly if things aren't tightened down.
