Serundo Auto 578 Led Bulb 211-2 41mm 42mm 1.65in for Car Map Light Dome Light, 6000k White Super Bright Interior Led Festoon Bulb,Pack of 4pcs

​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!

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.

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.

They are bright, almost too bright. The only downside is they don't completely turn off in my 2019 Nissan. They are not canbus compliant.

These bulbs are awesome! They are really bright! Not like the bulbs that come with most cars. If you go out at at night a lot or just want a brighter interior light these are worth it!

Installed in my truck about 5 months ago. Night and day difference versus stock, literally. A lot easier seeing in reverse.

Smaller than OEM, so I just pinched the slots tighter. Worked like a charm. Really bright and clear.

Used these in my 05 Subaru outback. Nice white light brightened up my while interior at night when opening the door.

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
