Review on JDM ASTAR PX Chipsets LED Bulbs: Super Bright Brake and Tail Lights in Brilliant Red by Jason Przystup

They were compatible with my 2006 Ford Expedition. This is from the Revain garage. They work, very bright turn signals, very bright brakes. However, when flashing while braking, the brake signal does not appear to be visible, at least in daylight. After turning off the turn signal, the brake light works normally. I have no idea if that's legal or not. If anyone found this to be a problem and found a solution, please let me know in a comment. The last thing I want is to be pulled over for a bad brake light. In addition, it was fully plug and play compatible. The signal LED was needed to avoid adding a resistor as I intend to convert all my signal indicators to LEDs. I like the sheen but am concerned about the crack indicator when turning.
