RCP -SUCAS-H7US- LED Headlight Canbus LED Compatibility Decoder Anti-Flicker Error Canceller Relay Resistor Adapter (Upgraded Version)

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.

I had problems with flickering and had code errors from my car. Purchased this since it had great reviews and it works. No flickering and no code errors.
