Then There Was Light
Size: 42mm 578 4pcs Color: white
Amazing improvement. Much brighter than the OEM part. Very easy install. The LED is a bit wider than the OEM bulb, not allowing it to point straight down, but is aimed slightly forward. Works perfectly. No flickering noted. This LED replaces the dingy yellow bulb with a sunlight, bright white.

great, just squeeze the metal tabs in for snug fit

Bright as heck and cheaper than 1 bulb at any store. Bright white hue makes the whole interior look cleaner, easy to install i just had to squeeze the tabs that hold the bulb in a touch so it would hold these bulbs tighter in the socket. Otherwise they would not have a good connection and would flicker or fall out. Low heat output compared to the bulb which burned me. ... show more

super bright
Size: 31mm DE3175 4PCS Color: white
So nice I bought them twice. I bought these months ago for a toyota pickup I have. They didn't quite fit (not the products fault, I got the wrong length bulb). I took a file and ground down the ends to make them fit. It still works fine and hasn't quit. I use the truck exclusively offroad and I've hit every bump, pothole, and hill. Its so bright I think you could use them to operate on someone in your front seat. I figured if I filed on them and bounced the truck over everything you can think of and they worked fine they must be good. I was needing to replace the interior bulbs in my 2014 Nissan Frontier (these were the proper fit without needing to file them). I was one bulb short to finish out the truck so I bought a second pack. When I open the doors it looks like a space ship landed. They are insanely bright. ... show more

So far so good. Bought these to replace some other LEDs I had purchased previously on Amazon that had failed after about 6 months. Hopefully these light bulbs will fare better & last longer than the previous bulbs. So far they are bright and do a good job of illuminating the inside of the vehicle at night when the doors are open. The appearance is a nice aesthetic compared to the old school filament type bulbs. The light is much more crisp and much brighter. There is no flickering upon first install and have been holding up great since I had them installed a few weeks ago. If these bulbs end up not lasting at least 6 months, I will update this review and the number of stars I gave it. ... show more

Good quality and price to upgrade from a regular bulb
Size: 31mm DE3175 4PCS Color: white
Excellent quality and price. Amazed on how this worked on an 2011 car using a normal bulb light, the change of brightness and visibility is huge. There's no Noise or heat output for now.

They are bright
Size: 42mm 578 4pcs Color: white
I have used LED's as replacements bulbs in numerous vehicles or boats. Yes, they are bright and use less power but come across the same issue with all I have used. Either the end barrels are too small in diameter so you need to "bend" the fingers so the led will touch and work or the LED's are too long by a fraction and cause that kind of issue. Ended up filing the tips down a fraction to fit. Knowing full well what I was buying as it states the diameter of the end barrel is .330 inch and I need a minimum of .360 inch. You wouldn't think that is much to be concerned about but it is. The LED almost falls out of the light socket "fingers". I had to "bend" the light socket "fingers" to have enough tension to hold the LED so it would work. It isn't the correct way to do it but I knew that when I ordered them. I used this on a 2002 chevy suburban engine hood light. ... show more
