Absurdly bright.
Absurdly bright. Like, really, really bright. Installed in the cargo light sockets on a 2003 Tundra. Lights up the bed, driveway, parking lot, etc. at night. All the guys in the weekly MTB group groan when I turn on the lights after the ride and blow out everyone's night vision. My only complaint is that they have started to flicker, which my technician buddies indicate is likely the bulbs failing. However I got about four years out of the pair, so still pretty satisfied with my purchase.

Sirius is a pretty good brand of LEDs, I've got no complaints so far, put a pair of the 921's for my 07 Pilot reverse lights and they're bright as daylight, makes the rear-camera useable at night.

What's the business?
Wanted to upgrade the reverse lights for my 2018 Toyota RAV4 since it came with halogen reverse lights. The brightness on these bulbs are great and it really illuminates the ground well when you put the car in reverse. Additionally, I have sirius LED turn signals with the canbus error free already built into the bulbs, just like these. Since putting these bulbs into my reverse lights, I have noticed that the car will lock and unlock wth the lights on without any problems. When I first made a full LED exterior upgrade to my car (LED headlight bulbs, LED turn signals, LED brake lights and tail lights) I noticed that the key wouldn't lock the car when the lights were on at night. Sometimes the key could lock the car. Sometimes I had to stand at certain positions around the car. Sometimes I just locked the car manually with the switch on the door before walking away. I assume it had something to do with interference from the LED upgrades. But after finding out about sirius LED brand with built in canbus error free whatever technology, the interference has gone away. However, there are some things to note about the 921 bulbs. Firstly, they do not fit like the halogen bulbs did. When replacing the halogen bulbs, I noticed that these 921 LEDs don't give a sense of security when placing them into the connectors of the car. The halogen bulbs "snap" into place, while these bulbs just "slide" into place. I removed them and replaced them several times in the connectors to see if I was doing something wrong, but that's just how they fit. I also had to do a double take and make sure I received the right bulbs for my car. I have gone over bumpy railroad tracks and bumpy back roads and so far they have not been disturbed or wiggled out of place. One thing to note is to make sure you look up your specific vehicle on YouTube to see how to properly replace your bulbs. I knew that I had to get underneath the car since the 2018 RAV4 has the reverse lights on the bottom where the rear bumper is, instead of near the brake lights like some other vehicles. But I didn't realize how time consuming it was just to get the connector out, remove the halogen bulb and replace it with the LED bulb, and put the connector back in place. I was able to put myself in a position where I could turn the connector and unplug it from the wiring harness to be able to work with the connector easier. And that was the passenger side. They say it's not necessary to train forearms themsleves since they are incorporated in pull ups, deadlifts, etc. But thankfully I train them and my left forearm was able to pinch and pull the wiring harness at the same time to free the connector to be easier to work with. The driver's side bulb ended up being harder because it was more cramped. What ended up happening was as I attempted to put the connector with the LED bulb back into the housing, the bulb slipped out of the connector and went into the housing. Unless you have the hands of deadpool after he got his hand chopped off, you couldn't get even part of your finger to fish out the bulb. What I thought was going to be a quick job ended up with me searching up how to remove the rear bumper from a 2018 RAV4. Had to remove a whole bunch of bolts, screws, and plastic retaining clips and then unplug an electrical harness to then be able to remove the bumper like legos. Then I had to unscrew two screws and remove two small plastic clips just to free the reverse light housing, to then be able to hold the opening of the housing down and shake like hell to have the bulb come out. It did come out and after putting everything back it worked fine. Overall, they are canbus error free, they are BRIGHT, and they make a slightly modern car look like how it should have came from the manufacturer. But they fit slightly lousy, doesn't give you a sense of SECURE security, and because of that it ended up giving me more work to do than necessary. Hope this gives you some insight when making a decision to purchase these bulbs, and I also hope the seller and manufacturer of these bulbs sees this and redesigns the bulbs to be more "secure" fitting like how the original halogens bulbs were. Will update to see how long they last before replacing. I think I've had the sirius LED turn signals for about two years now and still going strong. I expect the same from these bulbs.

Not for 2021 Equinox
Mixed opinions about these bulbs but only because they do not work in my 2021 Equinox. They stay on, very barely lit, but 100% stay on after they should be shut off when used as reverse lights. Contrary to this, I have used these in my 2021 Colorado for reverse bulbs and for cargo bulbs and they are terrific. So I guess be aware that there may be an issue with some models not liking the lack of resistance. But other models are perfectly fine with them. Still leaving the review at 5 stars because the bulbs themselves I think are great. Nice pure white light and super bright.

Excellent product!
Replaced my halogen backup bulbs on my 2025 Subaru Outback. It’s a super easy plug-n-play. Much brighter than the OEM halogen bulbs. Definitely worth the money.

Las instalé en mi RAV4 2021 sin problemas. Las luces funcionan muy bien y la instalación fue muy fácil. Me gusta que sean mucho más brillantes para que la gente las vea cuando doy marcha atrás. Realmente se puede ver la diferencia de brillo entre las antiguas y estas.
