When LED kit is installed in newer car models or cars with a computer controlled unit CAN BUS, often there is a error code showing on the dash board or the LED lights keep flickering and would not stay on. This is due to the fact that the LED kit is triggering a bulb out warning signal in your car's computer control unit. Where our LED Headlight Bulbs Stand Out: Latest technology Hybird EMC works for LED Conversion Kits, strong canbus chip built-in compatible even with the new car computer System. Our decoder is designed to balances out the current draw of the LED kit and would offset the warning signals on the dash board. It will also eliminate headlight flickering that is caused by the Vehicle's computer not recognizing the low wattage LED bulb. True Plug-N-Play: Easy to install, ture Plug-n-Play AMP connectors. Features: --- Directly plug and play, easy installation, --- Cancel Error Message cause by OBC (On-Board Computer) Check. Cancel Hyper Blink on LED Headlight. --- Permanently resolve the annoying LED headlight flickering problem --- Includes 2 pieces H1/ H3/ H7 decoder per order. Review: Works as expected - Works for a 2011 MB C300 using Hikari LEDs. I’m a little surprised at the variations in all the reviews for the decoders (not only this brand, but all the others, too). These are a pretty simple device. All they need to do is draw the same amount of current as a halogen bulb (LEDs use less energy/current than halogen bulbs, which is why many cars throw an error once they’re swapped with LEDs). But, on the downside, the decoders then have to dissipate that extra current draw somehow... in this case it’s dissipated as heat. Yes, the decoders get very hot! Don’t mount on plastic or near other wires or hoses in the engine compartment. If these are wired properly (positive/negative connections) I’m pretty confident they’ll work for most applications.
