i have a 70D with a premium package lighting. in the trunk, i have a light on the trunk (that goes up and down), and lights on both sides just below the parcel shelf mounting brackets. i changed them out to be a LED light strip, and all was working fine, until i noticed the past week, those parcel shelf lights dont work anymore (both sides) when i open the trunk. how should i troubleshoot this? i have checked to make sure all connected all plugged in correctly, and they appear to be. all help is greatly appreciated!
