I just installed my facelifted taillights and i found some problems. When my car is running, the left side has both the top red light and bottom red light on. And when i brake, the bottom red light shines brighter. But on the right side tail light, when the car is running, only the top red light is lit, and when i brake the bottom one is lit. What might be the problem? And does anyone know the solution? Thanks!
