2023 Upgraded Switchback LED Turn Signal Bulbs -T3 Series 4257

Lasfit T series 4257 switchback LED bulbs are specially made for front turn signal lights, two colors, amber and white, high brightness, and a built-in canbus decoder, no extra harness or load-resistors needed, plug and play, it's very convenient to replace the stock halogen turn signal light bulbs. Lots of people have got Lasfit T series LED bulbs and most of them are satisfied with their performance. T series LED bulbs are not perfectly compatible with some vehicles or can't work stably on some specific models and caused error code or hyper flash. Lasfit always deeply cares user experience and has upgraded T series based on customers' feedback.

Note: For 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.


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.

Turn signals are brighter and cleaner looking than the previous switch back turn signals. I didn’t have any issues at all with hyper flashing or any at all. Great product. All my vehicles have Lasfit lights.

Bulbs have been great. No overheating or anything. I love the switch back feature as it makes my truck just that much more sharp. They are bright and consistent with no flashing. I highly recommend them.
