ECU Tools, change Active ECU to HCML (or HCMR), find the data ID for F120 - Application Diagnostic Database Part number and click "Send to ECU" to read it. If it's 31427777 you should be good, for headlights all the way up through 2022 I believe.
Strange, I do not have either ECU's listed. They also do not show up in Vdash.
