How can I change settings for headlights? Mine come on automatically as soon as release parking brake. It’s in a 2010 Prostar. I checked in Insite but don’t see it in Parameters.

That is probably Daytime Running Lights (DRL). Those are controlled by the Body Control Module (BCM) INSITE is a engine only program. You need the Diamond Logic Builder (DLB) software to make changes. Annual subscription of about $648.00. Not really worth it. If you can find a competent stealership should be way less than that for them to turn it off.
DRL run at about 1/3 to 1/2 the power of night setting. Any particular reason you want them off? DRL is considred a safety feature although not mandatory. Post your VIN and I can probably get you the parameter/setting #.
