Review on 🔆 BRISHINE Ultra Bright 3157 3156 3056 3057 4157 3047 4057 3457 T25 LED Bulbs Amber Yellow 9-30V Non-Polarity 24-SMD LED Chipsets with Projector for Turn Signal Lights, Side Marker Lights - Pack of 2 by Kurt Manning

Put them in a C5 Corvette with derailleur and Hyperflash relay. They all light up, but no flash lights up when using the turn signal. So my problem isn't hyperflare and I wouldn't try resistors as they don't solve a serious problem. So revised review. The company was very helpful and sent resistors but was able to get it to work with a low powered relay. I bypassed my turn signal wiring because I had switches up front, but that relay was an old mechanism. one . I installed a weak amp and all the bulbs work as they should
