The Audi Q8, Aston Martin Vantage, Kia Proceed, Lincoln Continental, and Mercedes EQS all have horizontal tail lights.
LED technology has made horizontal light bars more common. The technology allows carmakers to install a horizontal light bar across a vehicle’s rear, usually connecting the two rear light clusters.
Aston Martin Vantage
The rear horizontal tail light on the Aston Martin Vantage gives this supercar a third brake light. The Vantage horizontal light bar is unique in that it shoots slightly upward from both rear light clusters and over the Aston Martin badge before running across the rear hatch.
