4257 4257NA CANBUS Error Free Anti Hyper Flash Switchback LED Turn Signal Light Dual Color-Standard Socket, 2 Bulbs

SKU#:T-4257D

• Our LED replaces halogen bulbs only. It does not replace HID or LED from factory.

• For a 2022~2024 Maverick Lariat, since the factory DRL is already LED, it is not able to use a switchback function, so the correct turn signal is T-4257A only in amber light.

• Please leave your vehicle make/model/year to cart before place the order, so we can provide follow-up support to you better in the future.


  • -Compatibility-

    1. Compatible with 2019-2021 Ford F-150, for front turn signal light.

    2. Compatible with 2021+ Ford F-250/F-350, for front turn signal light.

    3. Compatible with 2022 Ford Maverick XL, XLT, for front turn signal light.

    4. Replace factory halogen 4257 4257NA bulbs. 

    5. Please select the standard socket, the CK socket will not fit above vehicles.


     

    -Key Features-

    Built-in CANBUS System

    We know that, for 2019-2021 Ford F-150, 2021+ F-250/F-250 trucks, and 2022 Ford Maverick XL, XLT,  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 issues even though you finally find the 4257 LED bulbs replacement.

    Now, there is a good solution to abandon annoying resistor decoders. Our new version CANBUS 4257 will meet your need. LASFIT is the first brand on the market to publish built-in CANBUS Amber & Switchback 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 on the market.

    Dual Color Switchback
    Light up 6000K Xenon White for parking lights or daytime running lights (DRL); 3000K Flash Amber for turn signallights are 300% brighter than halogen.

    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.

    Worry-Free Warranty
    We provide 45 days money-back guarantee, 1-year hassle-free warranty, friendly customer service, and U.S. local customer support.

    Excellent product. Changed to all LED's on my 2023 Ford Maverick XLT. I found the only LED on my vehicle were the headlights and being with a Black Appearance package with vehicle it made my rear taillights somewhat less effective. It was a safety matter which I felt the LED's would be more effective for safety reasons. Made a 100% improvement, great purchase. The only lights left to change to LED are the front marker lights.
