Definitely worth it!

I got these to replace burnt-out LED bulbs in the closet and cabinets in the living quarters of my horse trailer. We took a chance, just going by the size and shape, because these are not the same as the old ones. They're nice and bright, and work perfectly!

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.

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

These lamps work well with other LED lights I installed in my cargo van. The brightness is equal, and I replaced the bulbs in my overhead cabin map/courtesy light fixture. I had to crimp the socket blades a bit to get a good grip on these lights, but they work well. Very pleased. Just aim them where you want the light to go in your fixture as these are not cob led lights. There is no flickering, the color is a bright white, and they are compatible to my gixtures.

Nice and bright

Bought to replace the old incandescent dome light in my 1980s Toyota pickup, which was quite dim. These are so bright, it feels like daylight in there. A couple of very cool things about this bulb are 1) you can spin the bulb in the clip/outlet to adjust the amount of light you get - in case it's too bright (seriously), and 2) these run very cool and draw almost no power so they won't eventually cook your plastic light cover, and you can leave your dome light on for days or maybe weeks without it drawing down your battery.

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.

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
