Battery draw when key is off

[Abramsenterprisesofny]

That makes a lot of sense hhow. When I manually turn off the work light everything shuts off for 30 seconds and then turns back on again. Other than this draining the battery it doesn’t effect anything and it turns off and stays off while the truck is running. I’m gonna check fuses today and start there. Any help you can send my way is hugely appreciated
