I searched but did not find this. The 13 VX200 has an annoying flicker if you encounter a sharp bump (e.g., the joint onto a bridge on interstate). Smooth bumps are fine and low speed is not an issue. The HID lamps seem unaffected, but you can see the flickering (the only other light that is on are the LEDs) on the pavement and on the backs of vehicles. No codes thrown. Electrical connections seem tight. Assessing if the LED is secure in the housing is tougher. Dealer is supportive, but is not keen to order new units and just test plus it is a pain to swap them. Has anyone heard of something like this? Fogs are off and high beams are off. I want to get this sorted early on if I can. Thanks.
