LED Festoon Bulb T11 39mm (Pair) – LG5108
A small change that makes a big difference. This pair of 39mm festoon LED bulbs provides a simple, direct upgrade for dim or unreliable interior and number plate lights. Engineered for a clean, bright output and complete electrical compatibility, they are fully EMC Approved to ensure zero radio interference.
It's often the small details that matter most. When you're looking for something in the cab at night, or need to ensure your registration plate is clearly visible, a dim, yellow halogen bulb simply doesn't cut it. This pair of T11 39mm LED bulbs is the straightforward solution—a direct, plug-and-play replacement designed for a perfect fit and immediate improvement.
Each bulb produces a crisp 135 lumens of light, transforming murky interiors into clear, usable spaces. But performance isn't just about brightness. At only 1.3 W per bulb, they draw a fraction of the power of old incandescent bulbs, reducing the load on your vehicle's electrical system. This efficiency is crucial for vehicles with sensitive electronics or older wiring.
Here’s the thing about many aftermarket LEDs: they can cause havoc with your radio, GPS, and other electronics. That’s why we engineered these bulbs to be electromagnetically silent. They are fully EMC Approved, meaning you get a clean, bright light without any frustrating interference. Built to operate reliably across a 12–16 V range, they are robust against the voltage fluctuations common in cars, tractors, and light commercial vehicles.
