Review on 🚗 SAWE - High-Performance 44mm COB Festoon LED Bulbs for Car Side Door Courtesy - Rigid Loop 1.73" LED Light Bulbs - 561 562 567 (2 pieces) - White by Bill Wieser

I tried them thinking the result might be different, but the results are the same: after installing one bulb (to replace an existing bulb), the rest went Lightbulbs in my cabin were either off or wouldn't turn on. . I tried another bulb (which looked like a circuit board on the back and LEDs on the other side, and the same thing happened). The SAWE bulbs didn't have a circuit board on the back, but that didn't matter on my car. I have returned the SAWE bulbs and need to further investigate the cause and in the meantime I need to move on to the bulb.
