Truck-Lite 30379Y – 30 Series, High Profile, LED, Yellow Round, 8 Diode, Marker Clearance Light, PC, Gray Polycarbonate Flange Mount, Fit 'N Forget M/C, 12V
Short Description (For Above-the-Fold Bullet Points)
Maximize commercial vehicle safety with the Truck-Lite 30379Y 30 Series LED Marker Clearance Light. Featuring an upgraded 8-diode configuration housed within an extended high-profile dome, this 2-inch round yellow (amber) lamp significantly widens peripheral light scatter for elite highway visibility. Pre-molded into a heavy-duty gray polycarbonate mounting flange for a secure, flush exterior installation, this dual SAE P2/PC combination light comes equipped with a premium Fit 'N Forget® M/C moisture-resistant connector.
Ensure maximum highway compliance and superior tracking visibility for your fleet with the heavy-duty Truck-Lite 30379Y Yellow Round LED Marker Clearance Lamp. Part of Truck-Lite's advanced 30 Series, this high-profile clearance light features a raised optical lens design. By increasing the height of the dome, this lamp broadens the overall projection path, making your commercial truck or trailer much easier to spot from extreme side angles and low-visibility conditions.
Outfitted with 8 high-performance yellow diodes enclosed in an impact-resistant polycarbonate lens, this lamp produces a rich, bright amber signal. Because it utilizes solid-state LED technology, it lacks the fragile filaments found in traditional incandescent bulbs—making the 30379Y entirely proof against the structural damage caused by severe shock, deep potholes, and intense road vibrations. The entire unit is hermetically sealed to keep dust, moisture, and road grime far away from internal electronics.
For unmatched structural rigidity, the light features a built-in gray polycarbonate mounting flange that aligns flush with heavy-duty vehicle body panels and frames. It integrates Truck-Lite's innovative Fit 'N Forget® M/C (Main Core) plug configuration, which forms a moisture-tight barrier to stop terminal corrosion before it starts. Best of all, its advanced engineering fulfills dual SAE P2, P3, and PC ratings. When mounted at a 45-degree angle, this single lamp satisfies both side marker and clearance light laws simultaneously—cutting your replacement component count, labor costs, and electrical draw in half.
