• restoring full functionality to the left-side rear and brake lights,
• reducing the risk of circuit interruptions, flickering, or light failure,
• maintaining correct resistance and connection quality within the lamp circuit,
• avoiding makeshift repairs that can cause electrical system errors.

For a commercial vehicle like the Transit Custom, functional rear lighting directly impacts driving safety and regulatory compliance, especially during intensive fleet operation.
