What would cause the headlights to be dim unless you pull in the lever for flash to pass on a 1996 Ford Aspire?

Dim headlights that brighten when you pull the lever for flash to pass may indicate a problem with the headlight switch or wiring. It could be due to a poor connection, corrosion, or a failing headlight relay that affects the power supplied to the headlights. Additionally, the issue might stem from a weak battery or alternator, failing to deliver sufficient voltage under normal conditions. Checking the electrical connections and components related to the headlight circuit would be a good first step in troubleshooting.
