So I'd like to say, yes these are awesome and yes they are brighter than the sun. They are ever so slightly thinner than the 7440 incandescent bulb and that's where my problems began. I go to put it in, it easily slides into the socket. Huh, weird, that it had almost no resistance. Go to put it into the socket and the bulb falls out into the headlight. Much like my ex girlfriend, the socket is loose because of all the things that were put into it. I don't think anything is big enough for that socket... These are high quality! Meaning the copper I can see is not magnetic. Neodymium magnet couldn't fish this thing out. Anyway, after removing my front bumper so I could get the bulb out, this time I put the LED in the socket and put some extra loctite around the edges. If the bulb blows I guess I'll replace the socket as well. These things are incredibly bright and no hyperblink without the extra resistor. Thanks! A few miles away, people will know I'm turning!

These fit snugly into the socket and are far brighter than the regular incandescent bulbs. This is a must upgrade for the rear turn signal bulbs. The only issue - this particular bulb is listed as NOT fitting a 2026 Subaru Outback, even though it's the correct spec. As a result, there were no Sealight brand LED bulbs listed when searching for the proper fitment. Read more
Nice and bright. Have had on my car for a while now. I've had other led license plate lights that were problematic but these work just fine. Read more

These worked on the 2015 mazda 3 gt I hatchback for turn signal in rear and are bright. They were a little tight getting into the socket I noticed but worked well right from the start. Read more
Awesome improvement over stock bulbs. This is my 3rd vehicle that I have purchased sealight bulbs for. The value is amazing. Easy install. Read more
“WOW!” The photo was taken near sunset and even with daylight remaining there’s no mistaking how much whiter and brighter the passenger side backup light is over the OEM bulb on driver’s side. When I later backed up after sunset I was amazed! Read more
Complete garbage!! I bought these because of the good reviews. I installed them for my truck bed cargo lights the end of July. Now the end of November, and one is out. Just 13 weeks they lasted. The truck is only my weekend vehicle, so a total of 26 days of use! Not to mention they are only cargo lights, so only on for a few a minute or two when I enter or exit the truck. I have purchased many LED bulbs over the years, and I have gotten some crappy ones that only lasted 8-9 months, but even those were fog light bulbs and were on many more hours. These 921 bulbs from Sealiight are the worst I have ever owned. Look elsewhere for something else. Anything else!! Read more
