Is there a way to stop the hissing noise from my headlight switch? Can it be plugged up? I converted my headlights over to electric due to all of the hoses being brittle.
Clearly you still have the vacuum signal hose connected to the switch. Cap it off in the engine compartment. Should be left hand side, just in front of the firewall.

Oh okay I'll give it a look and see. That would make total sense. The hissing noise gets annoying at times.
OK, not having any idea of how stock your car is. However, factory it had a check valve/line spliter that looks like this.
Should be located at the rear of the engine, drivers side. The smaller line is the vacuum signal line that goes to the over ride and headlight switch. Removing the smaller line and capping off its port should solve your issue. Or repair your vacuum headlights so they work properly.
In your second photo, centered up and down. Slightly left side to side. There it is just in front of the edge of your cruise actuator. The smaller of those 2 lines on that check valve/spliter. Remove the smaller line, cap that post of that vacuum check valve. Yes that line then goes into the firewall grommet. And the one next to it is the line coming out.
The smaller hose, on the right in your photo is sending vacuum to your headlight switch. Which for whatever reason you did not disconnect when you decided to convert to electric headlight door operation.
disconnect and cap that. The hiss you hear is a vacuum leak. You DO NOT NEED vacuum leaks.
It was installed buy the guy who did my body work and it was his first time ever doing the conversation. He says he is now going to do all of his corvette electric now.
That's all fine and good. Although myself I'm actually quite happy with the super simple, reliable, factory vacuum system.
Maybe just show him the vacuum line he missed. The factory vacuum headlight system has a control circuit and a actuation circuit. He kinda totally missed the control circuit. Which kinda tells us he has no idea how the factory system works. So when it doesn't, just switch it!
