AUXITO CANBUS Error Free 4-SMD 3030 Chipset 31mm (1.25 inch) DE3175 DE3021 Festoon 6000K Xenon White LED Bulbs Replacement for Interior Map Dome License Plate Lights Lamps (Pack of 4)

The DE3175 fits the map and dome lights. These bulbs fit snug and require a tiny pull on the metal retaining tab to remove and you have to pull this tab to install the new bulb. Don't pull on the tab much, but they do fit. No flicker and no polarity issue. The change in lighting is amazing. These 3030 chips make an incredible bright white light. Very happy with the improvement.

Nice upgrade from the original bulbs. These LEDS really brightens up the interior of your vehicle. So far so good!

Updates to the original review.After writing this review, I was (unexpectedly) contacted by the support department of Auxito. They kindly offered a replacement or a refund. Their customer service is wonderful. You can go ahead to order one even if you are not sure if this would match the socket of a light.-----The quality seems good. They are very bright. You'll be very happy if the socket fits.Unfortunately, in my case, 2 out of 4 were not a good fit. If you are thinking to replace DE3021 and DE3175, I'd suggest checking the form factor carefully.For my CR-V 2004,- Perfectly replaced interior dome light bulbs- Perfectly replaced luggage compartment light bulb- Did NOT fit glove box light (DE3021 bulb in the spec table). The terminal was a little too thick in diameter. I somehow got it squeezed, though.For my Corolla 2010,- Did NOT fit dome light (DE3175 bulb in the spec table).

Put one in the luggage area of my crossover. Very bright and happy with the level of illumination. However, the ends of the lamps are not pointy enough needed for the unit to stay in place compared to OEM. The cheaply built OEM housing would pop out the lamp when switching on/off. Had to modify the OEM housing to accommodate the lamp. If the lamp ends were built like the OEM lamps this would have worked better.

These are super bright, like crazy bright. But I like it. The whole car lights up light I have a spotlight from a movie set. There is no problem seeing anything now. No one will be hiding in my back seat.The main reason I got this was heat. The old bulbs got so hot in just a minute or two that you could not even touch the outside of the cover, and you could burn your hand on the bulb. These don't run hot at all.Make sure it is the right size for your vehicle. There are many bulb sizes that are very close, but not close enough to actually fit. I got one for a Nissan Leaf, it fit fine inside the car and the trunk. I used the spare in my Toyota Camry. It was not the right size at all, but I managed to force it to fit.

Left - Auxito DE3175 Right- OEM DE3175The caps on the ends of the Auxito DE3175 are much less acutely angled than the OEM bulb, which results in a longer effective length. In my Gen4 Subaru Outback, they were a very snug fit for the map lights and did not fit at all for the dome light. The package includes a nice plastic pry tool to pop off your cover without scratchingBrightness is much better than the OEM bulb, with a whiter color.Auxito should redesign the bulb to better match the OEM form factor

These fit and worked perfectly in my vehicle as all other Auxito products I've purchased thus far.

Installed without any modifications. Light is bright and can see whole car. Only issue it's now it's too bright. 😂 May be I will install a light diffuser film sticker.
