Review on ANTLINE Extremely Bright 1157 1157A 2057 2357 7528 2057A BAY15D 21-SMD 2835 Chipsets 1260 Lumens LED Bulb Replacement Brilliant Red For Car Brake Tail Turn Signal Blinker Lights Bulbs (Pack Of 4) by Jason Paredes

Build quality seems to be good, but time will tell. So far I am impressed with their light output. In my photo you can see the difference between these LED replacement bulbs and 1157 incandescent bulbs. A more noticeable difference is in the light falling on the ground from the taillight. Just check your turn signal for LED compatibility if you want to use it for turn signals. They can blink very quickly, e.g. when a lightbulb burns out, or not flashing at all if incompatible. In this case you need to update the flasher.
