This is a pair of rear lights to fit Mk2 Ford Sierra Sapphire models. The left hand side does have a crack on the curve. Both have a mounting bolt either missing or broken. Could be a good swap out on a fixer upper. Please check the pictures regarding the condition as they are not as bad as they might sound in the description. The part numbers for the light units are 90BG13A602AA & 90BG13A603AA.  Please check these are correct for your car before purchasing.
