Encaja perfectamente pero la iluminación no fue la mejor, compré otro para comparar de la misma marca y más moderno, la diferencia es mejor la nueva versión.

In my pics you will see a side by side with the stock reverse lights and these LED's on my Jeep Grand Cherokee. If its not evident, they are noticeably brighter. I'd say somewhere around 50% brighter. I have the tail light housings slightly tinted so these LED reverse lights were needed. I plan to also replacing the interior reverse lights now that I see how much better these are. As to longevity we shall see. But a most definite improvement.

I'll start with the good. These lights are definitely brighter than the incandescent bulbs they replace. They also run a lot cooler and pull less current. As for installation, I had two issues. The first was not the fault of the bulbs. It was not an easy task to get to the bulb holder in my 2015 Impala. It was even worse putting it all back together. Youtube has some videos on the process and they make it look much easier than it is. The second issue was that the holder is keyed and these new bulbs did not match the key. So it was impossible to push the bulbs all the way in. I can only hope that vibration does not cause them to fall out. Now for the main concern, and this one I don't know if it is going to be a problem or not. When the lights are "off", they stay on, but very dim. I can't see how anything about them would be causing this, so my assumption is, and if anyone can confirm or deny it, please do, the car is sending a low voltage signal to the bulbs to let the car's computer know if a bulb is out. On the original bulb this would not be enough to show up. But on the LED bulbs it is. It is hardly noticeable during the day, but at night it is quite evident. My concern is that this could possibly drain the battery if the car sits for a long time. It may be such a small current that my concern is unfounded. I would appreciate any feedback on this. I can't say if I would recommend these, as your particular situation might be better or worse. If they last a long time without falling out and without draining the battery, then I will be completely pleased with my purchase.

UPDATE #1: After doing some research I learned that the light goes dim because the high impedence of the bulbs prevents the BCM (body control module) from going to sleep. So it would not be the bulbs, but the BCM that would drain the car's battery. One fix would be to install some 6 ohm 50W resistors. I may do that. But my fix was to replace one of the LEDs with an original bulb. That worked. So for now I have one bright LED and one dim OEM bulb, and one spare of each. I wrote to the manufacturer describing my issue and they have offered to provide the resistors. I am waiting to see if the LED bulb will stay in place before doing any more work.

UPDATE #2: After installing one of the bulbs and leaving the other original bulb in place, I took a long trip. I went over the usual pot holes and railroad tracks and the new bulb stayed put. So even though it did not insert fully into the socket, it inserted far enough to function properly. In order to replace both bulbs without the problem of dimming, I contacted the seller and they offered to pay for a resistor kit which is the same thing used to prevent rapid flashing when the bulbs are used for turn signals. I ordered the resistors on Amazon and have received a refund for the amount of the order. It has all worked out quite well, and I can now recommend these bulbs.

Brake and turn signal light housings are designed to work with an incandescent bulb which are standard lengths. The reflectors inside the OEM housings reflect the light and project it appropriately. These reflectors can't do their jobs properly if the source position and direction of light are altered from that form which the housing was designed.
Most aftermarket bulbs are too long and/or do not cast light towards the socket as do incandescent bulbs. I know because I've tried dozens of different aftermarket bulbs.
These ibrightstars got everything right. They cast light 260 degrees literally, straight ahead, and most importantly are the same length as a standard 7440 bulb so that the reflectors can do their job as designed. They are also 95% as bright as the brightest ones I've tested. These also click in securely to the 7440 socket which is not always the case with aftermarket LEDs. The only thing that can be improved, which can be said also for all the others I've tested, is that the base is pretty large and this blocks light going rearward towards the socket and cast backwards to the rear of the reflectors. This must be a requirement for heat dissipation and the desired size of the bulb. Another really good bulb, albeit slightly longer than standard, is the diamond shaped ones by Lasfit.

If you use these on your Outback from the mid 10's, your traction control light will come on when you drive - seriously. The resistance being different than an incandescent bulb will freak out the system, and it will throw a code for the brake light switch circuit. If you have a car that isn't dumb, they work great!
