On 23/12 they were installed and indeed, as previously mentioned, they are very powerful. Their intensity is killing. No problem with the can-bus, everything works correctly. Hopefully they will last, time will tell.

Edit: On 15/05 half of the LEDs burned out from one and a week later the same happened to the other. Only 6 months of durability? I deduct one star only for this. I ordered new ones. It will be seen again in 6 months.

On 09/09 they burned out again. Very bright bulbs but without durability. What a shame!

They were installed in an Opel Corsa D 2014.. but they emit a very strong light that will definitely bother the drivers behind them at a dangerous point, potentially causing an accident! So be very careful!

It is not canbus installed in Seat Ibiza 2018 and it interfered with the sensors in the rear! In the rest of its usage, it seems to be fine

Happy New Year 2021 to everyone! Well, this particular bulb is VERY bright! At first, I thought it would annoy other drivers, and the truth is that it makes the flashes blinding, but once I saw that the few ultra-modern cars (with some exceptions) that are full LED (meaning they also have LED flashes) are just as bright, I realized that all flash bulbs are that powerful. The bulb was installed in a 2004 Ford Focus MK1 that had classic halogen bulbs. The difference in brightness is chaotic! In heavy rain or even fog, they will definitely SEE YOU wanting to turn or change lanes or when you have an alarm. I want to emphasize that there is no hyper flash phenomenon (that is, the fast on-off that happens due to a lack of resistors) because the bulb is canbus and has an integrated internal resistor; it worked perfectly for me without needing to change the flasher to LED type. Also, if you don’t want to change all 4 flashes but only the rear ones, it harmoniously coexists with halogen bulbs, meaning it can flash correctly with them; it just flashes faster and is "crisper" compared to them. I can't know how long it will last over time; I installed them front and back on December 20, 2020. I will write in the future about their durability. It also burns 16 Watts compared to the 21 Watts of halogen. Overall, it’s worth it because it draws less power from the battery! Pure color, genuine orange! However, don’t look directly at it; it causes afterimages in the eye... we said it’s a powerhouse of brightness! Highly recommended!

EDIT April 22, 2021: Because it was said that it is not Canbus... of course, it is! I’m providing a link from the official dealership that details the technical specifications. https://www.ledking.gr/products/led-oxhmatwn-12v/lampes-led-p21w-1156-can-bus/11831-lampthras-led-extreme-series-can-bus-2hs-genias-me-bash-1156-16w-12v-portokali-gia-flas-globostar-81239

EDIT April 26, 2021: One of the two I have for the rear flashes just broke, resulting in a fast blinking of the entire right side with the car's flashes, which is logical because the circuit that is created has failed. I had bought extras back then (December 2020) and replaced it, and the issue was resolved immediately. So before you suspect flash switches, etc., immediately replace the problematic one with a new one if it happens to you, and the problem will logically be restored immediately, as it was for me. I am waiting for a replacement under warranty (1 year) for the broken one. However, the lifespan may be short, although the other one from the pair is still working fine... time will tell. For now, everything is fine after the replacement. Maybe it just happened to me...

EDIT October 1, 2021: Since December 2020 when I installed them, I have reached a point where I have had to replace them all once. They do not have the endurance that they claim in the specifications for tens of thousands of hours, unfortunately. Perhaps because they operate at maximum to produce 1600 Lumen (!!) and at some point, one of the components burns out, the integrated internal resistor is lost, and the side where the bulb is located, e.g., the right side, starts to blink all 3 points (front, fender, rear) with fast hyperflash. Once you replace the one that has failed, it returns to normal. What I see that I ultimately don’t like is how strong they are!! There are times at night (especially then) when I don’t use the flash because their brightness is blinding! You don't even dare to look them in the eye, and surely the person behind is suffering and will be cursing me... it's an exaggeration how bright the flash is after all, and I'm already looking to replace them with fewer lumens. However, it's not easy to find ones with built-in resistance and low wattage (e.g., 5 watts); they are always 16 and above. Anyway, their excessive and absolutely annoying brightness (I've realized this after a while of use) is a reason for someone not to buy them... for this reason, I remove 3 stars from the 5 I initially gave. Think carefully before you get them... also keep in mind that they have no durability... I checked the car electrically, and there was no problem burning them, as I thought... they are probably made with cheap materials and can't handle it, and they burn out... all of them are going to be replaced! Look at how excited I was in my first review of them at the beginning and how disappointed I became along the way... coincidence??
