Marsauto DE3175 31mm LED Interior Dome Light Map Bulb Door Courtesy for Car 1.22inch DE3021 DE3022 Festoon Bulbs White Pack of 4

Almost a difference in between day and night compared to the standard bulbs!

These are much brighter than the original factory bulbs. Easy to install but I did find out that they are positive - negative specific. I first installed and the bulb didn't work. Tried it on the other light socket and it didn't work. Tried another bulb and it worked. Hmmm? Then turned around and the other one worked. Seems they need to be oriented correctly to function. So if they don't work for you, flip around and try the other way.

Fits and works as expected in my Mazda

Mars Auto stresses the importance of checking fitment prior to placing an order. Fair enough.We have a small cabin cruiser boat and are changing out all the original halogen bulbs to LED. The last new bulb required was a festoon design for a dome fixture in the head (bathroom). Ours is a very simple 12v design with two batteries, and circuit breakers for different functions (cabin lighting/water pump/horn, etc.) There is no CANbus microprocessor control as commonly found on newer vehicles, which can complicate replacement LED bulb selection.I emailed Mars Auto with a request explaining what we needed, (all the details) as above. Their first reply asked for the “vehicle” in which the bulbs would be used. I replied that it wasn’t a “vehicle”, but rather a boat, and re-stated the other pertinent information. There was no response from Mars. After a couple days, I sent the email again with a “second request” header.A different person replied apologizing that his colleague was apparently “busy” as explanation for the lack of action. This email requested a photo of the original bulb which had no part number, (the only markings were 12v 8w). I sent the pic.To this, Mars responded their bulb should work fine. I placed the order.The bulbs arrived in a timely manner, and were packaged well. I placed it in the fixture, and it indeed works!I realize there can sometimes be communication difficulties when different languages are involved. I also realize customer service reps can get busy, and/or “ignore” unusual requests. It certainly makes sense to order a bulb that will work properly, and avoid the hassles of returning something inappropriate.All’s well that ends well. 🙂 I would order from Mars Auto again, if the need arises. (One star deducted for the extra effort to verify fitment details).

I installed these in my 2006 Honda CRV; both in the Trunk and Center.. lowkey I should've just done the Center Lights, cause that is more than bright enough for the entire Car. But even with that said, I'm so glad i ordered these. The OEM Bulbs weren't cutting it, but these LEDs are the move!

These are much brighter than the OEM lights. I also like the white light, rather than the yellow of the OEM lights.I originally ordered these just to replace the burned out ones. I like them so much that I bought more to replace all of the interior lights. I just finished installing them and it is great. I can actually read a printed page under these lights pretty easily even with my aged tired eyes. I can't say the same with the OEM lights.Though it fit my Honda Odyssey just fine, they are wider than standard bulbs. So make sure you have the extra space for them to fit. You can guess from the picture of them being wider than standard bulbs whether it will fit your car.

Needed a new bulb for the interior of a 2005 Honda Accord. Could not really find the old style, and these had good reviews and were cheap so figured I'd give it a try.Installed them one at a time with the circuit off, then tested. Obviously they need to be faced down. But also found they are directional. On two of the had to pop it out and turn it around. So if they don't work, do this.These things are bright. Not only is it white instead of yellow, but it is bright. Like don't buy these unless you want people to see you in your car from a distance. But also makes it very safe when going to the car at night.Also went ahead and installed the set so it did not look weird with different brightness in the car.

While it fits on the front doors and cargo area of 2004 Toyota Sienna LE; however, it has only 12-SMD Festoon LED bulbs that makes it not too bright against having 24-SMD Festoon LED bulbs.

Purchased these for our 2018 Rav4 XLE for the back dome light. They are to big and do not fit correctly despite being listed as the correct size.
