Rinse the contacts with electrical contact cleaner, then polish them with fine steel wool or emery paper. The headlight slot will be the most difficult, so don't score the contacts with the screwdriver blade. Use a wood or plastic stick if necessary.

The silver terminals & the 3 copper ones at the L don't need to be cleaned. If the vehicle doesn't have cornering lights, the top 3 copper ones don't need to be cleaned.
