(888) 312-8812 Login SignupThe Peterbilt Turn Signal Service Kit is used during electrical service to restore proper turn signal operation. During diagnosis, technicians access the signal circuit and apply the components from the kit to address worn or malfunctioning signal elements. Once installed, the system resumes cycling between left and right signal states in response to driver input. The kit is applied only during repair procedures and does not alter normal driving behavior. Each component is positioned to support consistent signaling during lane changes and turns. The Peterbilt 480913X2S supports turn signal system servicing within the vehicle lighting network.
