My Pro Bono work is, by definition, cheap. But, when I'm on the clock, my hourly rate is through the roof! :dollar::dollar:
Prefer to use the word "Inexpensive" Remember the kiddie rides outside the supermarket? They had a small coin box with a chrome receiver on top where you dropped in the coin and a button that was pushed for the return. Id like to find something like that and mount it on a stand. wire it into the circuit with a cannon plug. Drop a coin and open the lights.
This one will do what you want. You can hook it in with just a trailer light disconnect plug. http://www.coinmech.com/product_profile.cfm?id=463 http://www.youtube.com/watch?v=bk6VwetiS2c
