Confusing Electric/Lighting Issue

Just got back from a week of camping, cleaned the trailer and parked it on the side. Went out this afternoon to get a few things out and noticed the trailer floodlight on. No biggie, I must of hit the switch while cleaning the trailer. So went in to flip the switch and found it was off, but the light is just lit as bright as can be. Flip the switch on and off a few times and nothing happens, light stays on. Here's were the confusion comes in, what the heck is going on? I finally just pulled the cover and un-pluged the bulb. Would this most likely be a bad switch?

Thanks for the help with my confusion.

    The switch is most likely corroded, buy a new one they're extremely cheap and easy to replace.

    Assuming this is a 12 volt light, it most likely is a bad switch since the switch should break the positive side of the circuit so no power can reach that light with the switch off.

    Now, if it was wired like the French used to do on cars and the switch breaks the ground side, then you could have a short to ground somewhere between the lamp and the switch.
