    The headlight switch is a command input to the instrument cluster which then tells the intelligent power module (part of the under hood fuse block assembly) to turn the lamps on. You really need to use an appropriate scan tool to assist with the diagnostics. It's likely there is a failure occurring with the intelligent power module, but that is not the only possibility.
