Review on Miniature Flashlight 💡 Bulbs Replacement - High-Quality Pieces by Ben Liu

I ordered these bulbs to replace the one that burned out in my handheld magafer. But none worked. I tested them and they showed good results on an ohmmeter. But I could get her to work in the light. I accidentally discovered that the lamp base is plus, and the filament is minus. My light was the opposite so I had to swap batteries. Lamps should be labeled as positive and negative.
