H4/9003 LED LED CANbus Decoder Anti-Flicker Harness | 6 watts, Error-Free Resistor Capacitor, 2-Pack

I used one of these to convert my old motorcycle headlight to an LED and it's pretty much plug and play. There is a warning saying that you should not install this in the headlight bucket because it gets hot, so I installed mine just outside the rear of the bucket. But I have subsequently been feeling the temperature occasionally, and it has not gotten that hot. Maybe because it's in the open air? Anyway, works well, easy to install.

I bought aftermarket led bulbs for my 2012 Mercedes SLK350 R172 and got the check headlight fault dash warnings on both left and right. I installed these and it fixed both dash warnings and fit inside the weather housing completely. I didn't have a flicker before or after installation. They are difficult to reach the connectors inside the car's housing but that is because of Mercedes and not these decoders.

Bought these decoders for my 2010 Volvo Xc60 T6. They worked for nearly 1 year until the canbus started to show errors with the bulbs, which were working perfectly! Knowing that it is really hard to get some working decoders for a specific car, I didn’t bother to get different once. So I bought an other set. Now this time around, they just started with canbus errors 2 months after installation! Not sure what the heck is going on! The leds installed are working properly, no flicker or any thing, but my dash instrument is showing an error!

I got these because of an LED upgrade for my truck. The headlamps were supposed to be plug and play, but the hi-beams wouldn't function and the fog lamps wouldn't turn on. Someone suggested using one these on the passenger side headlamp. They arrived fast, and installation was fairly simple. I opted to mount it on the frame, in case of excessive heating. It worked! All the lamps turned on, but only the driver's side hi-beam functioned. After I installed the second unit, on the driver's side, all lamps and beams functioned correctly. The only downside I could see with these is installation space. I have an older full sized truck, and finding a spot to mount the units was a little challenging.

Title says this is 100% paid out of my own pocket not no Amazon reviewer I picked this up today because I wanted to be on the safe side with my headlights that I have for LEDs as I am a delivery driver and I need to see because the area that I'm working at has a lot of wooded areas so for me to see I have to have very good pair of bright LED headlights now some of them I did run into flickering issues and that's what I just bought a different pair but that was auxedos that I was running and I swapped to the Terminator swappable colors with an app and those are good but they also recommend a canbus if you have any flickering issues since I don't have any flickering issues at all I just went on ahead and grabbed these as a just in case now since I'm running them I've noticed that they're just a little bit more brighter than usual and I do have the occasional little tiny flickers but that's just my car as is but if you're looking for a really good canvas that works give this one a shot but as in terms of durability I just got this today so I don't know The heat again I got it today I do not know and apologies if there's any spelling errors in this review as I am currently on the road right now doing a delivery so take this review as a grand assault as most people that have flickering issues or headlight issues that use a canvas system still have that remaining issue if that's the case then it has to be a ground within your headlight harness or your car's harness system in general anyways I have just arrived at my destination for my delivery thank you so much for reading this review have a wonderful rest of your night morning day or evening

Works good with my 2007 Dodge Ram 1500. I did have 2 issues: 1. Neither socket from the decoder to the LED bulb would clip in securely. I secured them with zip ties. 2. On one of the previously mentioned sockets, the center female pin was installed sideways. I was able to take it out and turn it in the right direction. Luckily I found a perfect place on each side to mount the decoder out of the way of any plastic or the elements, and meanwhile still being accessible if needed Overall I'm thrilled I can now run my LEDs, but this particular unit must have slipped by the QC. It happens.

Back on the road with no flickering or shut offs

Worked as they should

These decoders worked perfectly on my Mercedes C-Class, instantly clearing the "bulb out" error message. The installation was straightforward and plug-and-play, completely eliminating the flickering I had with my new LEDs. The build quality feels solid and heat-resistant, making it a reliable fix for sensitive CANbus systems.

Funciona perfecto, instale unos focos led en una Nissan Xterra 2002 y al encender los focos estaban en altas y al poner en la palanca las luces altas se activaban las bajas y solo encendía solo uno de los dos focos, con esto se solucionó el problema.

Hasta ahora no me ha vuelto a aparecer la advertencia de las luces fundidas en el tablero. Y fue muy fácil la instalación.

I used this product with some LED bulbs on a Jeep Patriot. Because of the pulse modulated voltage the vehicle uses for the head lights, LED bulbs do not work properly. This RC filter eliminated the problem (in this case, the capacitor is essential). I had to reinforce the cable at one of the connectors with some tape, but other than that, so far so good.

En mi caso no me funcionó en mi Jeep compass 2010, regular el problema del parpadeo, pero quiero prender las altas y no deja, lo tuve que devolver
