Signature Lamps
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
Each of the signature lamp assemblies consist of multiple Light Emitting Diodes (LEDs) that receive fused voltage when the ignition is in ON or START.
When the signature lamps receive fused voltage from the BJB, and the parking lamps are OFF, the signature lamps illuminate at full intensity. When the parking lamps are activated and the BCM sends a second voltage to the signature lamps to indicate the parking lamps are activated, the signature lamps operate at a reduced intensity.
