42mm 578 LED Bulb

Good so far, much brighter and cooler than an old style bulb that melts the lens. Time will tell.

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.

Nice and bright, easier to see what’s in the back of the car.

Fit perfect nice and bright white

Just got these today and installed them in the front and rear cabin lights in my truck. They are MUCH brighter than the stock incandescent bulbs, and provide a clean white light as opposed to the dim yellow of the stock ones. Only time will tell if the prove durable, but initial results are very positive.

Works great and brighter than standard bulbs

This fit the dome and trunk light of my 2020 Fiat 124 Spider perfectly. Much brighter than the incandescent bulb that was originally installed in the car. Took only a few seconds to install it.

Bulbs came well packaged inside of a plastic storage case and bubble wrap. Bulbs are very bright not sure about longevity.

Mucho mejor

rubbish

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
