T3 Series Switchback LED 7443/7444 Bulbs – Turn Signal Light with Can-Bus Decoder

Why Do You Need Lasfit Switchback 7443 LED Turn Signal Lights?

In 2025, Lasfit redefines turn signal performance with the T3 LED bulbs. Featuring a built-in CanBus decoder, these bulbs eliminate annoying hyper flash and error codes—no external resistors required. Equipped with high-output 3030 SMD LED chips, the T3 bulbs deliver brightness levels far beyond traditional halogen lights. What’s more, the switchback function provides a crisp 6000K white for parking lights and a vivid 3000K amber for turn signals—all from a single bulb. It's a smarter, brighter, and safer way to upgrade your vehicle lighting in one simple step.

Key Features of Lasfit Switchback 7443 Turn Signal Bulbs

·Error-Free Performance with Built-in DecoderTired of hyper flash and dashboard warning lights after installing LED bulbs? The T3 series solves this problem with a ceramic resistor built directly into the bulb, eliminating the need for external resistors. That means easier installation, lower costs, and a cleaner setup—just plug and play.

·Ultra-Bright Output with 20 SMD LED ChipsStruggling with dim halogen lights? Each T3 bulb packs 20 high-powered 3030 SMD LEDs and delivers up to 2000 lumens per bulb with a 24W output—providing maximum visibility for safer lane changes and turns, day or night.

·Quick, Hassle-Free InstallationThanks to their compact size and halogen-like dimensions, T3 LED bulbs are a breeze to install. Just twist out your stock halogen bulb, insert the T3 LED bulb, and you're done—no extra resistors, no special tools, and no stress.

·Built to Last – Intelligent Cooling SystemDurability meets design. T3 bulbs feature a full aluminum body, 8 heat dissipation hole, and a smart temperature control chip to prevent overheating. This advanced thermal management system extends the lifespan of your bulbs, ensuring they stay bright for years of daily driving and adventure.

-FAQs: Everything You Need to Know About T3 LED Bulbs-

Q1: What’s the difference between T-Series and T3-Series turn signal lights?

Brightness: T3-Series offers optimized brightness to prevent blinding oncoming drivers. Decoding: New resistor for longer, more efficient decoding. Lifespan: T3-Series has a heat filter for better heat dissipation and longer life. There are more details on the differences between the T series and the T3 series.

Q2: Can T3-7443 LED bulbs fit 7440 bulb size?

A: Yes. Lasfit T3-7443 LED bulbs are compatible with 7440/7441 single-filament halogen turn signal lights as well as 7443/7444 dual-filament halogen turn signals.

Q3: What are Switchback 7443 LED Bulbs?

A: If your vehicle uses 7443/7444 dual-filament bulbs, one bulb controls both the turn signal and parking light. Switchback LEDs change your front parking light from dim amber to bright white.

Q4: Are there two socket versions of 7443 bulbs?

A: Yes. 7443 bulbs come in CK and Non-CK circuits, and some vehicles may require CK-specific sockets. If you're unsure, here we prepare the CK version bulb table for you. If the bulbs don't work correctly, feel free to contact us for an exchange.
