Review on 🚗 SIRIUSLED 578 Festoon Light Bulb: Ultra-Bright 400 Lumens Canbus Error Free LED for Cars & Trunks - 6000K by Andrew Carrao

2004 Dodge Ram 1500 Normal Cab 4WD 5.7 Hemi 41mm length matches both my two map lights and rear window light. The two map lights were OEM #212-2 and the dome light was OEM #578. These 41mm SeriusLED string lights fit both locations, although I had to squeeze the tabs in the dome a bit to ensure a tight fit . I like the high brightness (see photos), but I noticed a loss of functionality, as follows: * The LEDs light up as usual when the door is open. * The LEDs will dim and then go out as usual when the door is closed. * The LEDs can be switched on as usual via the light control wheel without opening the door. * LEDs are NOT turned on by simply pressing the lens as before. However, they are turned off by pressing the lens. * No perceptible noises * The dimming and switching off function works quite well, only there is a slight stuttering at the end. * MISSING lamp off error messages * I can finally see what's in my dark fabric booth. Overall I am very happy with these LED replacements so far.
