Review on 🚗 HERCOO White LED Lights Bulbs: Compatible with Chevy 03-06 Silverado, Avalanche, Tahoe, Suburban | GMC 03-06 Sierra, Yukon XL | Upgrade Your AC Climate Heater Control by Hikeboy Ramey

After figuring out which end on the LED pins is positive (it's the longest pin, although I saw a + sign on the back corresponding to the shortest pin closest) I had no problems. Solder them to the desired connections. They are very bright and worth every penny! If anyone knows why the 05 Sierra dashboard stopped working after some soldering work please let me know. The digital display used to work with all sensors, but no, I only have turn signals.😬😬😬
