Partsam 10Pcs DE3175 31mm Festoon LED Light Bulbs White, Super Bright DE3021 3175 Bulb 6000K Canbus No Error 16-SMD-2835 for Interior Map Dome Lights and License Plate Courtesy Lights

They are advertised as 31mm festoon lights. Your best bet is to pop one of the lights you intend to replace and measure. If your OEM lights are 30 or 29mm then these will be pretty tight. Anything smaller and you need a different bulb.I used 6 of the 10 and all functioned perfectly in my 2011 Elantra. Be mindful that LEDs are polarity specific and the direction you insert them matters. If they don't light up flip them 180 degrees. More then likely that will do the trick.Lights themselves are great. They emit a bright light that is just diffused enough by the covers. Notice the extra light immediately and could not be happier. Will look to see if I can use them in my other vehicles (4 left over).

I've installed six of these to update the interior lighting in our 2009 CRV. All of them have worked fine so far. As others have noted, these are polar, so if they don't work right away, turn the bulb around and they should work. The color of the light is fine by me, though it is on the edge of white to blue, probably around 6000k based on what I know (although I couldn't find that information specified anywhere for these bulbs). While I like neither warm nor cool light but prefer neutral white, these are neutral enough for my preference.

They are a lot brighter than the stock interior lights. They have a slight flicker and tend to stay on (very dimly) after you exit the vehicle. This is a flaw of the vehicle itself and NOT the bulbs or the manufacturer. Adding a resistor to the lighting circuit would fix that. Overall they are a great product.

Decent brightness, but 6 out of the 10 defective. Couldn't even do all seven of the dome lights in my minivan.Update: Didn't realize these are polarity sensitive. All but 1 were good. Make sure you try them both ways when installing.

nice and Bright. But does not fit in the Visors.

All worked perfectly (easily checked with a 9 volt battery). Fit my 2007 Honda CRV. You have to remember that LEDs are polarity sensitive. If you put it in and they don't light up, turn it around.
