AUXLIGHT DE3175 DE3021 DE3022 3175 31MM 1.22”Festoon Canbus Error Free LED Interior Light Bulbs 6000K Xenon White, Super Bright 6SMD Chips for Dome Map Door Courtesy License Plate Lights (Pack of 6)

I purchased the AUXLIGHT DE3175 DE3021 DE3022 3175 31MM bulbs in 2025, and I have to give them 5 stars! These lights are incredibly bright with a vivid red color that really stands out. They were easy to install and made an immediate difference in visibility and style. If you’re looking for super bright red lights, these are definitely the way to go.

Product is great. They are perfect brightness and make zero noise. It came with 6 bulbs as listed and priced very well. I own a 2002 Mazda Protege5 and even though the sizes were off by a couple of millimeters compared to the old bulb, it still fit like a charm. I also installed the bulbs in my friend’s 90s GMC Sierra and they fit pretty well. Highly recommend for people looking for “Festoon” type bulbs.

Purchased and installed in my 2008 Honda Fit ceiling light housing. The OEM bulb is anemic, very anemic. I purchased another set that contained a 31mm festoon led bulb but it only doubled the light output of the original. Better but not good enough. I narrowed the choices to this set of 6 and another set that was rated at 400LM. However, it had 6500K light source -- a bit whiter than this one and it used a tad more power (2W rating). While I would have preferred to have the 400LM output, the LED's color is coolor and for me, 6000K is better than 6500K. After installing the 6000K LED lamp, the cabin lighting was much, much brighter. I am very glad I decided on going with these LEDs. Every Honda Fit owner who feels they need for more cabin lighting should consider buying this product.

Okay, it works, and the price is decent. But there is not protective tube around the chip, and the metal end caps are secured to the board by the flimsiest supports. When you insert the bulb into the holder bulb, the end caps bend in on both sides. Imagine taking a rectangular card and putting each end into a cup that just fits. Since there’s no support, the cups will easily tilt. This would be in contrast to a bulb where the LED chip was encased in a glass or plastic tube, and the end caps fastened to that tube. There is no tube—that is to say, there is no bulb, so technically, this isn’t a bulb. Also, this bulb is about 2mm shorter than the original 36mm bulb, and the end caps are slightly rounder. I’ll get a picture later. It still fits, but the vendor should at least get the dimensions exactly correct. Given that the bulb is kind of flimsy, I’m not sure how long it will last. But for now, it’s working, nice white light, not crazy bright like I feared, and definitely much brighter than the OEM.

Only time will tell but so far very impressed

I bought these LED cool white lights for the dome light of my car(97 ITR). It is nice and bright cool white color. It has a hint of blue. This light is slightly bigger than my old one, but it still fit. I had a hard time removing the dome light cover inside of my car. I needed that cover removed to put the new one in. There was one trick I have learned online. I used some Gorilla(duct tape can be used). Six inch strip I used. In the middle of that tape, firmly press on the dome light cover. Then, I grabbed the two ends of the tape and pulled down pretty fast. The cover came down with the tape. Before do the step I have mentioned. Make sure it is okay for the dome light inside of your car.

Installed on 2006 passat works great no errors

2004 Dodge Ram 3500 Quad Cab With the other LED bulbs we had, they all worked fine if you opened the door. However, you could not use them one at time (via over head console). To get any light in the truck with the doors closed you had to have all of the interior lights on, which is not what we wanted, or how they used to work. And in order to do that, you could not use the switch a the light, but had to use the knob/rotary on the dash. With these current AUXLIGHT LED festoon style lights, we are back in business. Just like how it use to work with the old incandescent lights. You can use one, two or all and no faint glow issues either. Also, no "LAMP" light on the dash or anything else. These are a direct replacement for the old, yellowish, outdated incandescent bulbs. Nice and bight and with a good color temperature too.

Worked great in my 2017 Hyundai Santa Fe. The OEM overhead/reading/door entry lights were a yellow color because they were incandescent. These are nice and bright white. I thought they might be polarity sensitive but they are not. I thought I only needed 1 bulb to replace a burnt out bulb - but I did replace all 6 in the vehicle because they are so nice and I figured if 1 burned out, the rest weren't far behind. I'd definitely recommend these. Hopefully I'll never have to replace these again.

Best Qualities and sharp lights

Tough built. Good quality lights.

These lights worked perfectly the only thing this that you have the squeeze the contacts closer together in order to get a tight fit. These lights replaced the dome lights in a 2014 Ford E350 van. Going to order another set to replace all the bulbs.

Bright White Light. After a few days of opening trunk at night I do notice a definite difference in brightness. Not only is light white but before could see in truck ok at best , now easy to see everything inside trunk.2010 crown vic
