36mm 6418 LED Bulb

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.

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.

bright, arrived quick,

Used in some systems, the bulb will not respond appropriately without an additional load to give the necessary feedback to the timer in the courtesy mode. Quite bright and an improvement over the OEM.

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.

​The Serundo 31mm LED Festoon is the perfect way to ditch those dim, yellowish factory bulbs. It’s a tiny change that makes a huge difference in visibility and style. ​The Best Parts: ​Crisp Lighting: The 6000K white light makes the interior look modern and much cleaner than halogens. ​Perfect Fit: At exactly 31mm (1.22in), it snapped right into the housing with no rattling or loose connections. ​Powerful Output: It’s bright enough to actually find things on the floor at night without being blinding. ​Solid Build: The heat sink design feels durable, and I haven't noticed any flickering or "ghosting." ​Bottom Line: An affordable, 5-minute install that completely refreshes your car’s interior. Definitely worth it!

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.

shipment was fast. the lights are perfect nice and bright better than OEM

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
