Review on Besbul 3157 LED Bulb Amber: Ultra-Bright 3157na 3156 4114 4157 LED High Lumens for Brake Reverse Tail DRLs Lights - Amber Yellow (Pack of 2) by Nguyen Taylor

Easy to install, but the lights will flash rapidly for the first second of use, then turn on and off in three familiar ways. This happens every time the turn signal is turned on. This means that LED capacitors do not have a large enough stored charge. **TO UPDATE**. The seller got in touch and offered a different bulb for the indicator. They promptly refunded the original purchase amount and sent me a link to what they thought was the best solution for my BMW. That's really great customer service if you ask me!
