My ‘02 2500 HD has the light and it’s 100% mechanical. It’s just a heavy metal piece that shorts a contact when the hood is in the upright position. I opened it up to clean the corroded contacts.OEM has a mercury switch IIRC. Could use that. Or there are other switch options like how your lights are triggered when you open your doors.
