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

• For a 2022~2024 Ford Maverick Lariat, since the factory DRL is already LED, it is not able to use a switchback function, so the correct turn signal is T3-4257A 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.

    What are T3 Series LED Turn Signal Lights?

    Upgraded Can-Bus Decoder System

    The most annoying thing for users is that compatibility problems such as dashboard errors, hyper flash, or working stably for a couple of minutes then starting hyper flash, frequently occur after replacing LED turn signals with LED bulbs. The built-in canbus decoder of T3 series LED bulbs increases the wattage to match the OEM computer inspection system and prolongs the decoding time, no error code, and you don't worry about hyper flash after working for a few minutes.

    Switchback Design. Softer Output Amber Lighting

    Some customers complained the output amber lighting of T series LED turn signal bulbs are a little bit too bright and glare at other traffics, so the amber lighting of the T3 series is reduced luminance. The amber lighting is equipped with 16 high-light flip chips, the bulbs provide 2000LM and 24W of lighting, and the white lighting is equipped with 4 flip chips, ensuring sufficient brightness for your vehicle. Additionally, the soft beam pattern helps prevent flashing to the side of passers-by.

    Built-in Intelligent Temperature-Control System
    Excellent Intelligent Temperature Control system will protect bulbs against excessive current and overheating and ensure a longer lifespan.

    Safety Protection

    While other LED bulbs on the market have sacrificed heat dissipation due to their small size, Lasfit has listened to user feedback regarding bulb lifespan and focused on developing T-series. These LED bulbs utilize smart IC chips and fuses, as well as aviation-grade aluminum for superior heat dissipation. Additionally, a built-in thermal insulation layer further enhances heat dissipation performance to provide a longer lifespan for the bulb.

    LED switchback turn signals

    I recently purchased the T3 switchback LED turn signals for my 2023 Ford Maverick, and I couldn’t be happier. Plug and play install in two minutes with no hyperflash. The running lights are bright but match the headlights perfectly, while the switchback turn signal is bright and lights up the road. It flashes with a little pinkish hue which was different, but I like it.

    Amber is more pink looking

    2023 Ford Maverick
    Installation is easy, have not experienced any hyperflashing, and I like the brightness of the flashing. But the amber is a little more on the pink side, not as orange as my side markers.
