Review on 🚦 LASFIT 3157 LED Turn Signal Light 3057 4157 Blinker Bulb – CANBUS Anti Hyper Flash & No Load Resistor Required – 2021 Upgraded Standard Socket Automotive Version – Bright Amber Yellow (Pack of 2) by Gregory Sirgio

I was very reluctant to purchase these bulbs as I had difficulty finding LED turn signals that would not flash without resistors or a new relay. Many other brands say "CAN BUS is error free" but still cause hyper flashing or error messages on the dashboard when installed. But I dared and bought these 3157 amber bulbs from LASFIT. After installing them, I was very surprised that they didn't cause hyper-flashing. However, I noticed that the bulbs don't turn on in parking light mode (they are dual bulbs that work as turn signals and parking lights). So I immediately thought they were garbage like everyone else. Before I took them I figured I'd call the company and see what they had to say about my problem. I was told that what I was experiencing was probably because I needed a CK base lamp. This is the same bulb, only the contacts are arranged differently. Some car models use this type of lamp. I was very hesitant because none of the other lights on my car matched this style. Anyway, I've ordered the CK version and the low version and they work great. No questions, no mistakes. I'm glad I called LASFIT, otherwise I would never have found out my car was built in this style. It is very difficult to find this information online. So far these lights have worked flawlessly. I am very happy with them.
