Review on 🔴 BRISHINE 4-Pack Super Bright LED Bulbs, Red, 3157 3156 3057 4057 3157K, 9-30V, Non-Polarity, 24-SMD Chipsets with Projector for Brake, Tail, and Turn Signal Lights by Ronny Welch

They're not bad, but they're not great either. Brightness is disappointing compared to many reviews saying how bright they are - they aren't. They work great as brake lights, but as reverse lights they are very disappointing. They don't light up standard bulbs at all and I would say they are a little dimmer in my taillights. They also cannot be used as turn signals because they have no resistance. These can be added but are not selected by default. The installation with all the lamps for my 06 2500HD Silverado is very easy. Remove the two screws holding the headlights, twist the wiring harness in each hole, pull out the old bulb and insert the new one. Reinstall. Ready. Being cheap they are decent and I will use them hoping they keep working. However, I will not buy them again.
