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.

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.

Works great

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.

Great quality

I've seen it before and I've already replaced bulbs in my Cadillac and they are very bright

High quality and bright

Great quality

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.

Iluminación perfecta, de calidad, solamente que la bombilla es muy grande y no encaja bien en los sockets de las luces que requieren.

It really lights up the inside of my truck definitely 10 times brighter than the old incandescent bulb. I did have to bend in the keepers a little bit. It wasn’t as thick as the original bulb, but it still holds tight now.

Good for interior lighting .Could be brighter for exterior lights.

Bought these for a 2007 Suburban since my trunk dome light went out. While working on it, noticed that the 2nd row LED lights and the cooling fins was touching the contact and causing them to not work. Had to slightly adjust the contacts away from the cooling fins to prevent them from touching causing the light to not work.Have worked perfectly since these edits. Alternatively had to angle the lights downwards on one side until modifications were done. Heavily suggest disconnecting the battery when doing this as this will require metal on metal contact.

Bright white light with a big improvement over stock bulbs. Installation is very easy and straightforward. Just test the light first to make sure the polarity is correct before snapping the cover back on. Overall, a simple upgrade that works great.

They are noticeably brighter than the halogen ones that were in my jeep and look like they are made of quality material. As per some reviews, I bent the tabs on my dome to hold these bulbs in better and checked the rattling and it had no effect on the light turning off. My only concern is even with the lights off in my jeep and the key not in the ignition the bulbs do give a slight glow. I tested it with each of the bulb and it was still glowing even 10 minutes after shutting the vehicle off and removing the key. due to that, I’m not sure I will be using them until I find a solution to make them shut off completely when the vehicle is off as to not drain my battery over time. I did test with the bulb that was already in there and it shuts off completely when the vehicle is off. Otherwise, I would’ve given it five stars.

First off, this product was tucked deep inside of a box that was used to deliver another item I had purchased. Luckily I checked before tossing the box, just be careful.First impressions, the bulbs look good, decent quality it seems like. Large heat sink for good heat dissipation. Packaging the bulbs came in was great. The bulbs were in a small sealed bag inside of a larger sealed bag so no moisture or debris could get in.Installation was very quick and easy. However. After I had installed it, before closing the plastic lens I went to turn the bulb on and it didn’t work. It was seated properly and very securely. To make the bulb work, I had to keep one side snug and the opposite side slightly looser which too me is the reason I’m giving 4 stars. Hopefully it’s an issue with this bulb and I can try with the other 3 but I’ll keep it in there until there’s a major issue.Other than that, so far no flickering. It takes less than 2 seconds to get to full brightness (it’s not instant like the halogen bulb). I can not report anything on the lifespan yet since it’s been in there a day but I’ll update if there are any issues.Thanks!

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.

Bought these for my 2007 Dodge Caliber to replace the rear dome light and the front two dome lights. At first I thought they were the wrong bulbs (despite being identified as the correct ones) because these are physically larger than the OEM bulbs, but they do fit. The electrodes at the ends are round which makes them harder to install, at least in my car, as the OEM bulbs have more oval-shaped electrodes.The dome light in the back was easy-peasy. Pulled out the old bulb, put in the new one, and it just worked. Floods the whole back with light which is pretty awesome since the hatchback area gets dark. I turned the bulb a bit so it was aiming more towards the cargo area than the back seats which was a nice little "feature" of the bulb. Otherwise, like I said, it just worked. Open the door and the light goes on, close the door and the light stays on for a few seconds, then it fades off just like the OEM bulb.The front dome light, however, is the reason why I'm giving this a low rating. There are two bulbs in the front dome light. They both go on when a door is opened, and like the rear dome light they both fade off after a few seconds. When they're off you can press either button (one for each light) to individually turn one of them on or off again. That's how it's supposed to work.Problem #1: With the LED bulb in place the passenger side bulb doesn't stay on consistently. It's almost like a bad connection with the bulb. It behaves like it's a problem with the socket but with the OEM bulb in place it works perfectly. Swap bulbs with the one in the driver's side and the problem stays with the passenger side socket. With the LED bulb in place it sometimes goes on, sometimes doesn't. Sometimes I can press the bulb into the socket and it stays on as I apply pressure. Sometimes if I spin the bulb in the socket it goes on and off. For awhile I was thinking that maybe the bulb's heat sink was shorting the electrodes since the bulb is a bit larger than the OEM bulb, so I put a little electrical tape on the edges of the heat sink to test that theory but it had the same problem. So it's very odd; ONLY the LED bulb ONLY in the passenger side socket has issues.But that's not all. With either or both bulbs in place (and momentarily working properly), if you open the door the bulbs go on full power and it's beautiful. After a few seconds they fade to off, as they should. But when you press the button to manually turn the bulb on, they don't come on -- or at least they don't fully come on. Instead of a blaze of white light you get super dim, super flickery LEDs that barely provide light past the dome light housing. It doesn't matter if there's two LED bulbs installed or one LED + one OEM bulb (in whatever socket arrangement). The LED bulbs always have this "low flicker" problem and the OEM bulbs work fine. This makes the LED bulbs completely useless for the front dome light; if you can't get full light from pushing the button then what's the point of having the LED bulbs?So I'm returning these and will try a different brand.
