I am adding a light bar to my 07 22ve. On the dash is a switch labeled tower light. the switch is a 3 position allowing you to light front, rear or both. My question is, I found the wires coming from the switch and they have crimp connectors already installed so you can just hook your light bar wires into them. I'm guessing that since it is pre-wired like this, it is already fused somewhere, and the switch can handle the load without a relay? The wires coming from the switch appear to be at least 12 gage, which also makes me think the switch is capable of handling the load. Am I wrong in my assumptions? If not, I must say that it is nice that Tige makes things easier by pre wiring for future add ons. One other thing. Does anyone know what type of light bulb is used for the navigation light on top of the tower. Mine is missing the bulb, and socket does not look familiar.
