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.

Great replacement for the Sylvania incandescent 578 dome light bulb on my 2003 Camry. Perfect fit. 41.5mm long / no need to force it into place, as I had to do with the Sylvania LED white light 578 bulb that I first tried (43.3mm long and a little fatter than this Serundo Auto 578 bulb). Amber light is bright but not too harsh / much better than the white light for me. Great value - 4 bulbs for about two-thirds the price of 1 Sylvania LED bulb.

The diameter of the contacts are smaller than the #578 incandescent bulbs in my 2014 Ford F-150. Fortunately since the receptacle is a spring clip just squeezed the clips to make a tight fit. The bulbs came in a nice plastic container which makes it easy to store and lessens the chance of accidental damage.

I'm happy with the lightbulbs replacement. It is very bright but we shall see how long it will last. I do recommend it because it fits ,not sure if it will last longer

Work great. Pretty blue color which looks cool at night.

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.

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.

Super bright, easy to install, but doesn't last long.

Se ajusto bien, los intercambie por luces incandescentes, ahora lucen más brillantes con mejor iluminación

rubbish

Mucho mejor

Extremely bright LED Bulb, so bright it's blinding. I installed these in my 2018 Dodge Challenger interior lights and I had to squeeze the contacts a bit, because these bulbs are slightly thinner than the original ones. No polarity issues, works great.

So…..LED is super bright. But to function properly as a dome light in my 2007 Dodge Ram 1500 I had to add a resistor due to flickering without. Fortunately there was enough room opposite side of connector to accommodate resistor. This was an extra I purchased for another project so size wise it’s a little overkill. I used an 8ohm resistor similar to: https://www.amazon.ca/4Pcs-Aaron-6ohm-Load-Resistors/dp/B00L4V9ECY/ref=mp_s_a_1_2_sspa?crid=1ILYY6EAO8TXH&keywords=led+load+resistor&qid=1642730741&sprefix=led+load+res%2Caps%2C154&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzQVU3TktZQVVHR1RXJmVuY3J5cHRlZElkPUEwNjkwMDg2M000TDNRR0I0N05QTyZlbmNyeXB0ZWRBZElkPUEwOTgzODc1M0VKTklVM0xYUjBETyZ3aWRnZXROYW1lPXNwX3Bob25lX3NlYXJjaF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl
