Review on Super Bright LUYED LED Bulbs with Projector: 2 X 900 Lumens, 78-EX Chipsets for Turn Signal, Amber - 3056, 3156, 3057, 3157 by Kyle Armstrong

They are definitely brighter than similar brand JDM-Aster 3157 (JDM ASTAR AX-2835) LED bulbs, the build quality is also better and even brighter than my 4157 bulb. They just use a little more energy. I believe the difference in brightness between "on" and the "turn signal" is not as good as the old bulbs. I'd like to save $2 if they don't pack them in a fancy box, but I suppose it helps if the bulbs bust when you touch them.
