Review on 🔦 Pair of 2 Canbus Turn Signal LED Light Bulbs 3157 3057 3357 4157 with Projector, White Yellow Switchback, 22 SMD, for Standard Socket (Not CK), with Load Resistors by Sam Kriegshauser

Works as advertised, they're bright and the resistors look decent. Installation took about 1 hour with soldered wires and correct wiring diagram (2012 Silverado). Make sure you mount the resistors on the metal to dissipate the heat and prevent the wires from melting. They have a slight delay in switching back to white after turning off the turn signal. This makes it look like an OEM feature. Note: 07-13 Silverados require 2 sets of 2 pairs, 4 resistors or you will get a quick flash.
