LED Bulb Type T11 41 mm (Pair) – LG5109

This T11 41 mm LED bulb pair is a compact upgrade for interior and marker lighting where reliability matters more than gimmicks. Drawing just 1.3 W yet delivering 135 lumens, it gives a clean, bright output without stressing the wiring. Designed for 12–16 V DC systems, it suits cars, tractors and trucks that need a simple, long-life, plug-and-play replacement.

If you’re still running old festoon-style filament bulbs, you know the issues. Heat. Vibration failures. Dull light. These T11 41 mm LED bulbs solve that in one quick change. You keep the same footprint and fitting style, but gain modern LED efficiency and a much more stable light source.

Each bulb runs at 1.3 W, so current draw is low and predictable. That’s important on older wiring looms and in vehicles with multiple interior or marker lamps fed from a single circuit. At 135 lm per bulb, you get clear, usable light without glare – ideal where you need to see switches, controls and paperwork, but don’t want to blind the driver at night.

These bulbs are plug & play. Remove the old 41 mm festoon, clip the LED in, and you’re done. No resistors. No coding. No polarity games for standard installations on 12 V–16 V DC systems. They’re suitable for mixed fleets too – cars in the yard, tractors in the field, rigid trucks or light commercials on the road – anywhere a 41 mm festoon-style lamp is used for interior, courtesy, step, or marker lighting.

The LG5109 is EMC approved, so it’s designed not to introduce electrical noise into your vehicle systems. That matters if you’re running sensitive radios, CANbus-based controls or GPS equipment. It helps keep nuisance interference and diagnostic headaches off your desk.
