Overall sentiment: negative
Customer reviews:
On a positive the bulbs are bright.  The issue I have may not be with the bulb but with me or my Jeep.  I natal led them without much difficulty and the light up perfectly.  You may have to flip them from one side or another to get them to light (something to do with polarity).

Anyway, my issue is that when I have my car running the light bulbs have a slight glow.  No an issue in the daylight but at night it's a problem.  I truly don't know what's causing the bulbs to get power. My incandescent bulbs work fine and don't glow when shut off. 
 I was very hopeful in this product.. I installed lights only to find that 3 of the 6 lights working. So then I tried the other 3 and 2 more did the same..not pleased with the product 
 Bright enough to illuminate the plastic cover over the dome light but that is about it. 
 Not bright at all, but I guess you get what you pay for. 
 Received 4 bulbs and 2 of the 4 did not work at all. I tried flipping the bulbs to change polarity and still nothing. I used a different bulb and it worked fine so 2 out of 4 were good the others just worthless 
 Some worked some did not my assumption is they feel enough are included to get a couple working bulbs.

Be careful when installing as some vehicles with multiple dome lights will have to be grounded seperatly once using led bulbs. 
 Too long 
 first 4 pack i got only had three lights in it all three of them strobe when turned on and will not go all the way off when not in use company sent me another 4 pack 2 of the lights did not work other two had same problems

The flat led part is to long to fit in a Silverado dome fixture Something they left out of the description 
 Worst product I've purchased on Amazon. Not bright at all and what's worse is some of the LEDs don't even work (not that the lights would be much brighter with them on anyway). Also they don't "truly" fit the housings so the contacts aren't snug. Removed them immediately and put them back in the box.

You can have these back and I'll try my luck at Pep Boys or something. 
 Didn't work well in either my 2014 Mustang GT or my BMW X5. They light up but they flicker nonstop.
