I put the round SoCal LED fogs behind the square on my 2014 F6B without any issues. Purchased the OEM Honda accessory round LED fogs and they didn’t match the white color of the SoCal LED headlights. The OEM Honda accessory LED fogs were more yellowish. Replaced them with SoCal LED fogs which matched the white hue perfectly.
