OXILAMUpgraded 7440 7443 LED Bulbs White for Reverse Lights, 4000LM 600% Brighter, 7441 7444 T20 W21W LED Lamps Replacement for Backup Tail Brake Turn Signal Parking Lights and DRL (Pack of 2)ClimatePartner certified

Going on my second pair of these and they have been the longest lasting bulbs I've had in a while. The first pair lasted me almost a year. I'm guessing the cold killed em so I'll update if these poop the bed. Otherwise great especially the brightness. I have 35% tint covering my turnsignals on the brake housing so these being as bright as they are is great.

I replaced another set of LED backup lights that I was not happy with. These lights are fantastic, super bright and when looking through my backup screen it looks like I have 2 high powered flashlight shining in back of me. Really a great set of lights.

Very tight fit on my 21 Ram. Felt as if i pushed them in the socket anymore i would break them. work well tho.

Edit: I got a chance to install the bulbs in my wife's car and they work as advertised. I can't tell if it's because the load circuit built into the bulb just happens to be sufficient for her car and the included load resistors would still be necessary for other vehicles, but they definitely do include a load circuit and driver in the bulb. (It was raining and I didn't have the ability to put them thru exhaustive tests with meters, plus I don't know what resistance the car looks for.)The bulbs are super bright and have a color temperature that's easier for the human eye to see than the OEM amber halogen bulbs. No one's going to miss it when my wife changes lanes or makes a turn. The instant on/off of the LED vs the fade in/out of the halogens is very eye-catching and, along with the added brightness, should increase visibility especially on bright days.I suspect that there's a holdover in the packaging method that put the unneeded resistors into the packaging. They may have originally shipped with non-CANBUS bulbs and were just packed in by mistake. (I guess I've got two extra load resistors and heat sinks hanging around for future projects now, because these aren't going back.)Review adjusted to 5 stars. While there was some initial confusion that could have been easily avoided, the product works as expected and advertised. Well worth the price and easy to install in the car I'm working with (2013 Hyundai Genesis Coupe).See Edit. For now I'm giving these a 2 star review based on the difference between the ad and the package. These arrived today and, full disclosure, I haven't installed them yet. The ad lists that there's a built in load circuit, but yet these still come with load resistors in the box and instructions for how to install them.That the resistors are included rather than sold separately is nice, however, the point of CANBUS bulbs is to not produce errors and avoid cutting into the wiring with load resistors (as well as avoiding the minor hassle of positioning the resistors to dissipate heat). These were advertised to not need resistors at all. At this point I can only assume that either the bulbs don't have built in load circuits as advertised, they're potentially underpowered and will only avoid errors and hyperflashing on some cars, necessitating the use of additional resistors to compensate, or I somehow got the wrong item. Nowhere in the ad is it mentioned that anything other than the bulbs themselves are included, so seeing load resistors in the box was an unpleasant surprise.I'll be installing one bulb tomorrow to see if it produces an error or hyperflashing. I'll update my review accordingly. If the resistors are required to make these truly error free, I'll be returning them as they're for my wife's car and I'm not willing to cut into her wiring when I know there are bulbs that don't require it (I have several in my own vehicle and two in her front signals, but I didn't want to use switchbacks that might blind drivers behind her or appear to be reverse lights while they're not flashing).Hopefully this is an oversight, or mistake, but I wanted to give fair warning to anyone who considers purchasing these before I can determine the reality of the situation. I'll update when I have more information.

super easy to install - super bright led - I am using mine as a rear turn signal. the 7440 fit my 2015 q50.

Love it so far definitely better than the factory ones!

It fits great in the bulb housing and it does not flicker. So far it works great. Thanks

These are perfect. Replaced front turn signal bulbs with these. Nice darker shade of amber, bright, and best of all, No "hyper-flash"!

These things have a good deep color, and work as they should. HOWEVER, they only lasted 3 months before they started flickering and eventually died. I'm not certain it's due to the cold weather, but I purchased them in December and they died in February.Would NOT recommend if you're looking for longevity. There's another brand on Amazon that I've had for well over 2 years and they're out lasting these ones.

The media could not be loaded.  Truthfully, this is a good product. The build quality is very good, miles ahead eBay consumables. But the most important thing is they do indeed have built-in resistors, and they work! All 4 bulbs are replaced and I don't experience any hyperflash. The light pattern, even if not that important for a turn signal, is quite nice, there are no dark spots nor scattering.The only aspect that I'm a bit skeptical about is they are SO BRIGHT, it's nearly as powerful as headlights, and standing at one meter from the car looking at the bulb during 3-4 flashes dazzled me. I hope it won't be annoying for people around. I think you better not let them on during a 5-minute red light at night if you care about people behind.I've only driven a few cars with OEM LED turn signals by night, I don't remember them being as bright. You can still make your own opinion with my video.This is still a very good bulb, and few are the options for LED bulbs with built-in resistors that are not lies. They fit very well into my Lexus GS300's bulb plugs, as opposed to cheap bulbs before that weren't even made the same, some fit, some were lose. They modernize and enhance very well the looks of a car, especially if you have an older luxury vehicle. If you're OK with being careful not to let them on for too long at night with people around, I recommend them.

*Edit:Hyperflash on both side after less than an hour,. possibly only 5-10 mins of use.The bulbs fit my car fine, but the resistors are hit or miss, my left side works, my right side does not.The right side slows down after a min or 2, but qill hyper blink when I press on my brake again.Pros:FitVery brightCons:Resistors are hit or miss.Very bright(if this bothers you)On the fence about returning them, & trying another set.*I can't really review the Longevity just yet, I just installed them, & hit a speed bump.

I installed these on the front of my Suzuki XL7. Fit perfect, no hyperflash, no canbus errors...and super, bright.They are great for daytime use but I think they might be too bright at night.I pull up to a red light behind other stopped cars and my turn signal illuminates everything including all the reflective tapes used in an intersection. I never knew there were so many. I can see the reflection of other cars' turn signals but they are obliterated by the light from these bulbs. Lane changes on rural highways light up the trees and brush at the side of the road.Can a turn signal be too bright? Dunno. We'll see.
