What Circuits Does Amber Side of Dual Face Trailer Light part # STL53ARPB Work With  

Updated 02/17/2026 | Published 06/13/2024

Question:

Does the amber front facing LEDs activate with braking or only with turn signals. I am assuming both since it is only 3 wire

Hey Justin, the amber side of the Dual Face Trailer Light part # STL53ARPB is going to function just like the red side. It will be a dimmer illumination when the running lights are on and then it will get brighter at same time as the red side when blinker or stoplights are applied.

Hey Justin, how did the Dual Face Trailer Light end up working with your turn signals and brake lights? Your update could make it easier for the next person wiring the same setup.
