I've replaced a pair on daughters 2010 with cheapy ones but they flicker and throw a message of low beams out while not. I think the ECU probably senses it because the LEDs don't use as much current. Anyone have luck with a specific brand LEDs?

 

Check and see if the LED manufacturer has an ECU compatible version. The ones I bought had two versions, ECU and non-ECU. The non-ECU version works fine in my old Chevy truck. They will not work in the Volvo due to the way Volvo runs the headlights. The flicker is the result.

 

I have installed these into an 08 Jetta which did flicker with a simple LED bulb.These runs fine and bright as hell.Pretty cheap too.
