Description

The Lasfit T3-4257D is a switchback LED turn signal bulb, part of the T3 Series, designed to replace standard 4257 bulbs. With an output of 2000 lumens per bulb and a 24W power draw, these LEDs significantly enhance visibility for safer lane changes and turns. A key feature of the T3-4257D bulbs is their built-in CanBus decoder. The switchback functionality means they operate as white for parking lights and switch to amber for turn signals. These bulbs are designed for direct replacement and are a popular upgrade for vehicles like the Ford Maverick, with specific mentions for the 2022-2026 models. While the product is generally plug-and-play, it's always recommended to verify compatibility with your specific vehicle's lighting system, as some vehicle configurations or other aftermarket modifications might require additional considerations.
