Review: Removes the annoying LED flicker. - 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.
Review: Fixed headlight dash warning. - 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.

### ⭐ Doesn’t work consistently with 2010 Volvo Xc60 T6
*by R***A on May 8, 2026*

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!
