Marsauto 578 LED Bulbs Extremely Bright 400LM 2835 Chipsets for LED Interior Dome Map Door Lights Bulbs 211-2 212-2 569 6411 6451 41mm 42mm 1.65inch 6500K White RV Interior Lighting (Pack of 4)

Bought these to upgrade trailer. Almost a year in and zero problems. Nice and bright and sip a fraction of the watts the incandescent do.

These bulbs are great. I can’t comment on how long they will last just installed them, but they are very nice and bright. They fit a 2010 Yukon XL, 2002 Yukon XL and a few others.

Easy to assemble, brightness is good

These worked in my 2001 Dakota. Nice and bright, but not 5 stars because they tend to randomly stay on at a very dim low level after they turn "off" automatically or are turned off. I am assuming at this point the current draw is too low to really affect my battery life if the truck sits for an extended period of time. At least I hope so.

Plenty bright solid build not really sure about them being 400 lm each, but I’m using them on my m35 for the door lighting can’t complain they fit great. I like the white color I would recommend.

Easy to install, but you MUST buy the LED converter cable, otherwise you will get an error code. That cable is only about $10. LED is bright but you sometimes hear the fan sound of the cooler.

Installed on a 2008 Range Rover Sport HSE, replaced the original Xenon bulbs. It's not easy to find an LED bulb which actually fits and works on the Rover for a reasonable price. Definitely brighter, whiter, and casts a wider beam, so it's a good upgrade. I definitely like the idea that you can turn the bulb by hand after installation, so the beam pattern can be lined up properly (usually with the LEDs shining sideways), but has enough friction to hold it in place. With most other adjustable bulbs you have to remove the bulb and loosen some tiny screws and try it again. This is far more convenient. On the Rover the tricky part was what to do with the the Xenon igniter which is usually directly attached to the bulb, so for now it's tucked into the lamp housing cavity next to the bulb, and hopefully vibration does not cause any damage. Another concern is how long will these bulbs last, knowing that the cooling is relying on a small high RPM fan? Kept the original bulbs just in case, but for now these are great.

High quality and bright

These are so bright, amazing quality!

Para interiores del vehiculo estan muy bien, iluminan mejor que las incandecentes.

Installed this in my 2020 Chevy Suburban Premier and the brightness is night and day compared to the stock D3S factory bulb.

Nice and bright.. just like having daylight in my 2017 Hyundai Santa Fe XL

Excelente iluminación
