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.Softer Output Amber Lighting
Some customers complained T series LED turn signal bulbs are a little bit too bright and glare at other traffic, so the T3 series is reduced luminance. Equipped with 16 high-light flip chips, the bulbs provide 2000LM and 24W of lighting, 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
Safety Protection
While other LED bulbs on the market have sacrificed heat dissipation due to their small size, SEKO 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.
