    -Key Features-

    Built-in CANBUS System

    We know, for 2019-2021 Ford F-150, 2021+ F-250/F-250 trucks, and 2022 Ford Maverick Lariat, they have 4257 factory front turn signal light bulbs in the socket. There are not too many aftermarket 4257NA LED bulbs options in the market. They don't have CANBUS system to anti hyper flash issue even though you finally find the 4257 LED bulbs replacement.

    Now, there is a good solution to abandon annoying resistor decoders. Our 2021 new version CANBUS 4257 will meet your need. LASFIT is the first brand on the market to publish built-in CANBUS Amber LED turn signal lights, when most products of LED are not canbus error free on the automotive aftermarket. We are confident that these bulbs would give you an extraordinary driving experience!

    Directly Plug and Play
    CANBUS system can prevent 90% hyper flash and error warning. No need to add extra resistors or parts anymore. They are designed to directly plug and play.

    Brightest LED Turn Signal Light

    The brightness will be reached 12W per bulb. It's the brightest LED turn signal light in the market.

    Dual Brightness Function
    Upgrade function for switchback coming with the brighter mode for turn signal light and the normal mode for DRL/driving indicator.

    Intelligent Temperature Control (ITC)
    An excellent Intelligent Temperature Control system will protect bulbs against excessive current and overheating and ensure a longer lifespan.

    Safety Protection
    Built-in MINI fuses to protect the bulbs and your cars against the instantaneous high current. Safer installation and use.
