I popped these into my Nissan Titan map lights and wow does it make the interior look updated. Along with changing the door and footwell bulbs, the interior is now bright with a crisp and clean look that's also functional as I can see things better at night when I open the doors at night. No flickering, no fit issues.

Excellent light for a great price. I can see everything inside my 2003 F-250 6.0l truck. My last LED dome light was as bright as it gets years ago, now they make better perfect fit lighting and brighter too. Very happy with my order, will edit with the length of time each LED lasts, hopefully longer than 1 year.

Super bright and no halogen heat to burn the lens or socket.

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!

Bright. Really like the (true white) color. Easy to install on my 07 RAM 2500. However they don’t come on as a reading light when the switch is pushed with the ignition switch off I think because of the amperage draw is not correct with the key off, but they do come on as a reading light when the switch is pushed with the engine running. They also come on when the doors are opened (key off and on). I’m happy with them overall.

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.

Very Bright, I bought both the white and blue LED dome lights for my 2004 Ford F-350 and they work great. No complaints at all.Would recomend to buy.(If not sure if they fit I went to Sylvania's vehicle light bulb fit and then you input your vehicle and the bulb position and it will tell you)
