    Built-in CANBUS is Very Important for LED Turn Signal Light

    We know, most LEDs may cause hyper flash & error code when they are replaced on the turn signal lights due to LEDs low-consumption, energy-saving performance. If there isn't enough resistor value to meet car computer, extra resistor decoders will be needed.  

    Now, there is a good solution to abandon annoying resistor decoders. Our new version CANBUS 7440 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!

    -Key Features-

    Plug & Play Installation

    CANBUS system can prevent 95% hyper flash and error warning. No need to add extra resistors or parts anymore. They are designed to directly replace the factory halogen lamp.

    I honestly love these turn signal bulbs, super bright than stock. You won’t go wrong purchasing from LasFit, I mean the bulbs are just simply amazing. And when I say they’re bright, I mean they are super bright. I haven’t taken any pictures or videos yet. My photographer is out of town that does my car photography. But I will update with a video and some pics as soon as he arrives.

    Very easy to install. Extra bright but I didn't expect the running light system not to work. The original lights had 2 filaments. These only have the 1 set of terminals. Other than that I'm happy.

    Hello Luke,

    Thank you so much for sharing your product review.
    Upon reviewing your recent order, we noticed you selected the T-7440A bulbs, which feature a single filament design. Should you be in need of a dual filament bulb, we recommend the T-7443A model. For your convenience, you can find it here: https://www.lasfit.com/products/amber-amber-7443-led-turn-signal-light-bulb-anti-flickering.
    Please don't worry, if you want to try the dual filament bulb, we will help you exchange them.

    We also reached out to you through our customer support email cs@lasfit.com to follow up.
    Look forward to hearing from you, thanks.

    I love how bright these bulbs are, its the second car I've filled with lasfit. My only downside so far is that if you're sitting in traffic with your turn signal on for 3-5+ minutes, eventually it will hyperflash, which I'm assuming is from the bulb over heating.

    Hello Greg,
    
    Thank you so much for sharing your product review.
    We're so glad to hear that you love the brightness of our bulbs and have chosen to use our LED bulbs in multiple cars.
    Please don't worry, that is a normal phenomenon for the built-in resistor design of turn signal light, considering the life span and canbus function.
    Our bulbs have resistors built in to avoid hyper flash, once the bulbs are used for a few minutes (2-5 Minutes), they will reach a high temperature and hyper flash, which is the safety feature to avoid our bulbs burning out quickly.
    Please turn off and cool down for about 1 minute, everything will resume as normal.
    
    We also have reached out to you through our customer support email cs@lasfit.com to follow up.
    Feel free to email back to us if you need any further support.
