These are soooooooo bright. I LOVE them!!!

I have had issues in the past with replacing the dome lights in cars with LEDS and they just weren't bright or just weren't nearly as omnidirectional as a standard halogen bulb would be.

Not these guys!! They might be a little on the pricey side compared to other LED bulbs, but they are worth it.
Let the pictures speak for themselves. Both pictures were taken at night, one with the rear glass open, and the other with the glass (tinted btw) closed.
If you turn these on at night it will feel like daytime on the inside

Super bright! So much better than my horrible stock JKU interior lights...

Installed one of these LUYED LED bulbs in my 2016 Jeep Wrangler Unlimited. The LED light fit fo the rear light dome great, I just had to bend the metal holster a bit (OEM dome lights for Jeep Wranglers are a bit larger compared to the LUYED LED lights). If I didn't bend the metal holsters, the light would flicker because the fit was too loose.

Def a major upgrade to the interior lighting, I would highly recommend buying a set (Jeep Wranglers only need 1 LED Light for the rear dome, so you can keep a spare).

Installation took less than a minute, only tool I used was a butter knife to pop the dome light cover off.

I've been through quite a few brands of "festoon" style LED bulbs and I can honestly say, these are the brightest, whitest and most durable"‹ I've ever come across. I bought the 330 lumen ones and they too are wicked bright! But if you want to blast your whole cabin or cargo area up with enough light to probably grow questionable "herbs" in, then these are for you. WARNING: Do not install these in map lights that are close to your face, because when you turn these on, your night vision will go right out the window! After seeing first hand how bright these are, I "modified" (bent the piss out of the clips) my Honda Accord's dome light to make these things fit and it was well worth it! Yes, there's some slight buzzing/whining if your vehicle has the auto fade/dim out feature but, it's honestly not that bad; lasts a whole 2-3 seconds. I even disassembled the ends of one to adapt it to fit a horizontal style dome light in a 2003 Dodge Ram single cab; 194 wedge style base. For those of you who own said truck, mod these to work in your dome light and never look back... literally. You can take even the best 194/168 LED replacement for horizontal dome lights and multiply it's output four times and it still wouldn't touch the brightness these things put out. Just buy them and make them fit however you can!

If you need super bright 578 lights, then these are for you. They are amazingly bright and light up a pretty large area when my tailgate is open. I have 2 of these installed in my tailgate ('03 Dodge Caravan). The rest of my vehicle is using a lower lumen rated LED which is fine for the overhead console. I don't think I would want these everywhere in my van because they are just so darn bright. Super impressed with the brightness.

These are fantastic LEDs. I wanted a bright white light ... and I got it. They are quite bright but not too bright. They are 42mm festoon and 6000k intensity. Which is White/blue-ish.

I installed these as part of of an LED conversion on my 2001 Porsche Carrera 911 (996). These fit: main dome light / luggage compartment / Engine Bay. This LED conversion looks fantastic. Most people think my car is a 2010+.

Very happy with them and would buy again. If your worried about the light being too bright ... get the next step down which are the 330 lumens.
