Key Features of Lasfit Amber 4257 Turn Signal Bulbs
-
Error-Free Performance with Built-in Decoder
Tired 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 Chips
Struggling 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 Installation
Thanks 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 System
Durability 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.

Great bulbs bright during the day and they look a whole lot brighter at night. 100% these ate great. Attached are some photos. I would upload a second video to see from drivers view bit only allows me to upload 1 video
Sorry, my review posted for these bulbs should have been for the same bulbs but red for the taillights.
Purchased these for my 2025 Ford Maverick Lariat red versions for the taillights and they hyper flash when sitting still. As soon as I accelerate the hyper flashing stops and they return to normal blinking. Update: I am very pleased with the company, they have been very easy to work with.
Hello Michael,
We're very sorry for any confusion and inconvenience may cause.
The hyperflashing behavior for the D-4257R rear turn signal/brake/tail light you have described, where the lights hyper flash when the vehicle is stationary but return to normal blinking when you accelerate, can be attributed to low voltage.
When the engine is not running or idling, the voltage supplied to the lights may drop slightly, causing them to hyper flash.
As soon as you accelerate and the engine revs up, the alternator generates more power, increasing the voltage supplied to the lights.
This higher voltage level restores the normal blinking pattern, resolving the hyperflashing issue.
In daily usage, the engine keep working before activating the lights to ensure they receive an adequate and stable voltage supply, so please don't worry.
If you don't like them, we will completely understand and offer a return label and make sure you get a full refund.
If you have any further questions or require additional assistance, just let us know, thank you.
Feel free to email back to customer support email cs@lasfit.com if you have any further questions.
Sincerely,
Lasfit Customer Support Team
I just installed the front turn signal LED's on my Tremor, they look great!! Install was super easy, just took about 5 minutes total. Can't wait to see them at night.
Led bulbs are great. Along with their customer service. I had a bulb that started popping out continuously 7 months after purchase and they sent me new ones and they worked great.
