100x’s better and BRIGHTER. Cannot wait to see them at night. Very satisfied so far however cannot speak to the durability of them but impressed so far. Plug and play and no flicker so far. Absolute pain in the butt to install the headlights just because tiny little boy hands are needed but I got it eventually. The pic with the yellow circle is the new vs factory HID.

These lights work really well and were plug and play. The light is very bright and seems good so far. The install on a GS350 was not easy due to limited space, but it worked out.

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.

Bought these Hid Lights due to the good reviews it has, overall they came in and installed them on my 2018 GMC Sierra 1500 and they sure make a difference. These lights are very bright and they are brighter than OEM lights just as some of the reviews say. For now I’m very satisfied just hoping to see a good life span on them 🤞🏽.

Work amazing!

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.

arrived on time, excellent quality Thank you

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

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

Excelente iluminación

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.
