H4 Canbus Decoder

First off. Only a handful of people stated the type of vehicle they are buying these for so I was a little iffy. But I have a 2016 jeep compass. And my led headlights kept flickering to the point I just wouldn’t drive at night. It has stopped ALL flickering. It was compatible with my jeep. The product seems durable but not sure yet time will tell. The only thing that would have been better is if it came with longer zip ties. But other than that it fit and done it’s job!

These fixed the highbeam indicator light on the dash and my fog lights are working again on a 2001 Ford Escape

Does not work, my lights still flicker. Would not recommend

These are a breeze to install and straightforward. Just connect the plugs where they need to go and light them up. Got the H11 connectors and they fit perfectly. Includes little zip ties to ensure they don’t flop around. The connectors give a nice click and also have some rubber gaskets to keep moisture and dirt out. The box is encased in aluminum, so they seem durable. LED lights came on with no flickering, codes, or issues. Great price too!

Works great

Gadt shipper ..and good product 👌

Nice construction and easy install but it did not 100% eliminate my bulb out warning on the dash from installing LED fog lights. The warning light would come and go depending on the day.

This worked great! My Fog lights would turn on, but also turn on my high beams at the same time. So if I needed my fog lights while running my low beam headlights, my high beams would turn on. This decoder fixed the problem. I can turn my fog lights on and off with out any problems. My high beams turn on when I need them. Everything works normal like it was designed by the factory.

These work perfect.tried a few other types but didn't work.these stop the flickering perfectly

I purchased this D-Lumina H4 Canbus Decoder pair after upgrading my older halogen headlights to modern aftermarket LED bulbs. My car's computer system immediately threw error codes and the new lights started hyper-flashing, so I needed a high-performance capacitor link to stabilize the power load. Pros: Instant Error and Flicker Correction: These decoders worked exactly as advertised. The 10000UF capacitor system instantly eliminated the dashboard warning lights, stopped the bulb rejection issues, and canceled out any buzzing radio interference. Premium Heavy-Duty Build: The intelligent digital circuit boards are housed in a rugged aluminum box that acts as an excellent heat sink. Plus, the metal braided cables feel incredibly durable and actively block electrical current interference. True Plug-and-Play Installation: The all-in-one design makes setup incredibly straightforward. The H4 connectors matched my factory harness perfectly, clipping tightly into place with zero splicing, trimming, or wiring modifications needed. Weatherproof Security: The components feature a 100% waterproof seal, giving me complete confidence that rain, car washes, or winter slush won't cause short circuits under the hood. Cons:Bulky Under-Hood Footprint: Because the aluminum heat-sink boxes and braided cables are built to be robust, they add a bit of bulk inside the engine bay. You will need to take a few extra minutes to zip-tie them securely away from moving engine parts or extreme heat sources. Not Compatible with HIDs: Keep in mind that these digital smart decoders are engineered strictly for LED conversions and will not work if you are trying to resolve issues on a high-intensity discharge (HID) setup. Final Verdict: An absolute lifesaver if your vehicle's computer is acting up after an LED upgrade. They are durable, easy to install, and deliver a reliable, flicker-free beam pattern.

Las luces funcionan muy bien, sin esto se apagaban de repente, y ya no ocurre eso

I installed this decoder to fix a slight flicker I was getting in my high beam bulbs when they were running as daytime running lights (DRLs) on my 2007 Toyota Camry. It worked exactly as expected — the flicker is completely gone on the side where I installed the decoder. To test it, I recorded a short video: the left headlight (without the decoder) still shows a faint flicker, while the right one (with the decoder) is perfectly stable. The difference is clear. If you’re upgrading to LED bulbs and notice any flickering, especially in DRL mode, this little unit is definitely worth it.
