The Kenworth Turn Signal Switch is a reliable and practical replacement for OEM# K301D182. Designed with a 12V standard and a modular plug-in, it allows for easy OEM replacements without the need for rewiring. With a 10 bulb capacity for hazard warning and 5 bulbs per side for turn signal flashing, this switch exceeds Class A, SAE, QQC, and FMVSS108 specs. Its heavy-duty unitized construction ensures durability, while the positive detent provides a better "driver feel" when signaling. Additionally, it features integrated stop lamp circuitry and is sold individually for most Kenworth truck applications.
