Truck owners, this heated mirror assembly is exactly what your Peterbilt needs! It fits multiple models from 2005 onward including 335, 340, 357, 382, 385, 386, 325, 330, 348, 388, 389, 365, and 367. The complete driver side set includes a 16x7-1/4 inch heated stainless main mirror plus an 8-inch convex heated mirror for wider visibility. You get all the mounting hardware - main bracket arm, extension arm, support bracket arm, and aluminum black mounting brackets. The heated function is crucial for maintaining clear visibility in cold or wet weather conditions. Plus, there's a 3-inch round LED marker light with 30 diodes (red/amber) that's DOT approved, perfect for installing under the mirror for added visibility. The stainless construction resists corrosion and the assembly feels solid and durable. Installation is straightforward if you're familiar with truck repairs. The mirror provides excellent coverage and the heating elements work quickly to clear fog, frost, or light ice. The LED light is bright and energy-efficient, adding that extra safety margin during night driving or poor visibility conditions. If your current mirror is damaged, fogging up, or the heating element has failed, this replacement assembly will restore proper functionality and visibility. The quality matches OEM specifications without the dealership price tag, making it a smart choice for maintaining your Peterbilt's safety and appearance.
