Marsauto DE3175 LED Bulb 31mm Festoon LED Bulbs White 1.2inch Super Bright 300LM 6500K 2835SMD 3175 DE3021 3022 3021 for Car Interior Dome Map License Plate Lights 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.

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.

These lights were a perfect fit! I have had a lot of experience with inexpensive LED lights that seem to be a smaller or larger than the socket not these, they were a direct fit for my application. Lights are bright and after months of use still I have had no issues. The built in heat sync keeps them cool as advertised. Would recommend! Will be purchasing more soon!

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.

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.

I just installed a Marsauto 578 LED DOME Light in my 2002 GMC Sierra 2500HD (Duramax w/ZF - 650 6spd manual box), and all I can say is... WOW!! What a Huge difference in the brightness of this dome light. The 2002 GMC (& Chevy version) 2500 HD... is NOT "CANbus" equipped, so have NOT had Any "issues" with the light. I have also installed LED dash cluster (green led's) lights, as well as replaced the whole door / entrance light assembly with the led unit.... AMAZING Light!! Just make Sure, that your vehicle is Compatible (CANbus, or not) with which ever LED's that you're considering.... "Most" vehicles AFTER 2006, use Canbus technology, and if so... you NEED to buy CANbus compatible LED's, or you Will get "error" codes, flickering LED's, etc, etc. Save the hassle, and just fill out your vehicle information (Year, Make & Model) at the top of the page, and it will tell you, if the LED's you're considering (or ANY part, for that matter) are Compatible for your vehicle. The ONLY Negative I have about LED's in general, is... that the light intensity Is NOT Dimmable, in automotive use... at least NOT in Pre-CANbus equipped vehicles. Many vehicle manufacturers began installing the technology in various models in 2006 and later vehicles. So, "buyer beware" and definitely check for compatibility with Your vehicle. You Can use :CANbus" technology LED's in a NON - CANbus equipped vehicle, but for the LED's to operate correctly, you will need to get a CANbus Coder unit and wire in into your electrical system.... "How To" Directions will Vary for each vehicle.... but it Will save you a LOT of "headaches" with Canbus Tech. LED's in a NON - CANbus vehicle. One way to avoid the headaches, also... is to just contact the LED Supplier, using their message Contact tab, and just ask them which of their products is right for Your particular vehicle... just make sure you give them the Year, Make & Model of your vehicle when you contact them.

I don’t want to sound like everyone else that claims they don’t write reviews, but it’s true I don’t. This company deserves one though, 100%. I seen one too many reviews on fitment. All I can say is before buying anything you should confirm with your vehicle specifications. On another note, these lights are awesome. I won’t speak so much on durability and will update if any issues but as of today (9/5/25) I installed these lights and made a big difference from stock on my 2012 GMC Sierra 1500. I had the stock lighting in this truck and man was it hard to deal with. Installing these made a huge difference and also feels more luxury as crazy as it sounds. If you are looking for brighter lights from the stock “yellowish” lights these are definitely the lights you want to buy. Took me about 5 mins to install all four bulbs.

Worked for about a year. They were cheap so not a bad deal for a short term solution. They were nice and bright but they would flicker. Great visibility while they worked. They fit perfectly in my 2008 Accord. Not the worst and they lasted for about what I paid.

These are so bright, amazing quality!

El precio es más que bueno, brillan y duran muy bien. Antes usaba Phillips o hella pero son bastante más caros. Definitivamente los recomiendo.

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

The bulb size is like almost perfect. The fit was a bit tight in my 2016 Kia Forte5 SX dome lights but I was able to get them in with very little effort. They're plenty bright however they're nothing special. I bought similar bulbs from a different brand and when I compared the new bulbs to the old bulbs they were basically identical even down to the PCB traces. Overall I have no real complaints. The price was good and I got enough bulbs to replace the ones I got if they ever fail. Only issues where that the fitment was slightly not perfect but nothing that stopped me from using the bulbs.

Excelente iluminación
