Led Decoder D1S D3S/D2R/D3R Canbus Resistor Anti-Flicker Harness Headlight Bulb Decoder for LED Headlight Warning

I picked up these decoders after i installed 2 led h7 bulbs in my promaster and which worked for like a week before one headlight would just turn off immediately. I found this product searching through a fb promaster page. When I got them I thought I would only need to use one since only 1 headlight would go out but wasn't the case after the easy installation on just plug and play the led headlight worked again. I ended up installing both decoders and have been using them for about a month now with no issues. Super easy install just plug them in between the factory plug and headlight plug. If the headlight doesn't come on just flip the decoder plug and it will come on.

This is exactly what I needed! I recently installed the aftermarket headlights along with a different companies hid kit. When the key was in the accessory position the lights would be fine. While in the run position however, the lights would flicker. Looked at several different reasons why and found that if your car has running lights they draw right from the headlight. This solution beats what any other company has. Super easy install, literally plug and play. In the video provided, the driver side has the flicker problem as described above before the decoder was put in while the passenger side has it already installed. The result is instant. I’ve had no issues since. One thing to keep in mind is that they are polarized so if the headlight does not come on once installed, it may be just a matter of flipping the connector around.

About 1 year ago I bought a set of BeamTech LED headlights for my 2015 Nissan Rogue. The lights worked flawlessly for about a year. A few weeks ago my wife mentioned that the passenger side headlight is now randomly flickering and shutting off on its own. This was a scary situation driving in heavy rain during darkness. She would get flashed by oncoming traffic when ever the light would go out or flicker. I decided to try this LED anti-flicker harness and see if it would help the random headlight issue we were experiencing. The harness was easy to install and I quickly learned you have a 50/50 shot at installing it correctly because of LED polarity. I swapped the harness connector 180 degrees and was able to get the lights to function correctly. So far it has been about 2 weeks and no headlight flickering observed. So far, so good. I am happy with this product.

Purchased these in Oct '19 for my headlight LED upgrade. Straight forward install and all seemed well. Fast forward to Jan '20 and my headlights start flashing randomly. I remove them and the headlights work great, put them back in - flashing resumes. Return window closed only 30 days after purchase so I'm stuck with them because they made it all of 90 days. Don't make my mistake! Avoid!!

Still getting some flickering…

My 2007 Honda Accord is not fully compatible with the 9005 highbeam LED replacement that I purchased (which is from Amazon; more interestingly, it comes with a decoder already); the LED could light up but there is always a DRL error message in the dashboard (the highbeam also serves as DRL in this case). I tried a relay device but it did not help at all. Later on, I found this Anycar decoder on Amazon; however, there is conflicting information on the website about the compatibility with 2007 Accord: one said yes, while another said negative. The seller does say it is not for 2006 Honda Accord(?!) which is also the 7th generation ones. What is going on? Maybe the only way to know is to try it by yourself! (This is also the reason why I made a purchase from Amazon.) Bang! It does work for 2007 Honda Accord! Error free! Confirmed! It is very easy to install; it just took me a few minutes and I am very happy that this device finally solved the problem. -----------------------------UPDATE---------------------------------------------------------------------------------- Although the DRL error message was gone, I just found another potential "problem": since 2007 Accord uses highbeam as DRL, the 9005 should be dim, not at full strength, in the DRL mode theoretically. It is unfortunately that 9005 is full strength output at DRL mode, that is, this 9005 is always super bright when it is on; I do think other drivers in the opposite traffic direction would be happy to see this full strength highbeam thrown at them. Now I have two choices, either to disable DRL function or go back to traditional halogen bulbs even though it is not as bright as LED. Maybe newer vehicles have a separate lamp specifically for DRL and that could be the only way out.

My fog lights made me get a headlight out notification, hooked these up an it went away.

My 2014 GMC Sierra had led lights and I thought the driver side light died- I bought a new set and when I first plugged them in they worked with the old canbus decoders I had. My problem ended up being that the old canbus decoders were going out and without them my headlights would shut off after 10-20 seconds once the truck computer didn’t detect the light and shut off the power to one light or the other. I tried a cheaper brand first and the headlights wouldn’t work at all. So glad I have these a try, I thought I was going to have to switch back to halogen.
