What do you do if you have more lights than there are switches in the OPS switch bank? I.E. 4 mid range lights on the front of the roof and 2 work lights on the rear of the roof.

Recently bought an 850D with the ops top, ops rear sliding window, hinges, windshield, door frames...and no doors! I assume the previous owner knocked one off. If anyone has any laying around (long shot) let me know. Thanks!
