Late to review these. Working great, bright , easy to install

Shorter ones did not fit tight and LED flipped around to inside the headliner. These are snug and provide excellent illumination. Easy, no tool, no polarity or dash warning issues.

Fits my 2002 Corolla like a glove. I tried similar bulbs before, but they were 31mm instead of 30mm, and also burned out after a few months.If these don’t last, I will update the review.

A+

These bulbs work very nicely as replacements for our sail boat’s 12v cabin lights. As a bonus, they arrived in only two days — as opposed to the lengthy lead time quoted on the order page.

Excellent quality can-bus led bulbs. Installed in a 2012 VW Touareg and I didn’t have any errors or problems at all. They also dim perfectly like the original halogens. These are well made and you can see the consistent quality; every bulb looks identical and perfect. There is a difference between these Chinese made bulbs. ONLY time will tell if they last but so far so good. Great price too.

Only needed one bulb to replace the ceiling light in my car but it wasn't too expensive and it provides more light than the original bulb it replaced. The fact that it is polarity insensitive is cool since you can't plug it in wrong.

Didn't even last for 6 months. 2 of them died with 5 months so I replaced them with the other 2 and those died today.
