My DIY halogen setup works but is clunky. I am in the process of streamlining and I was wondering if there is any serious disadvantage to not having a switch. I plan on just using auto trailer connectors and connecting or disconnecting them to turn the light on or off. This will save me the effort to weather proof and wire a switch. I also noted that there are commercial halogen systems with no switch. Is there an advantage to switches other than convenience?
