where is the switch for porch light located normally?

Hi Guys,
Have received a lot of information from previous posts and appreciate your kindness!
Our trailer works well so far, the problem is that we could not locate the switch for the porch light...
I looked everywhere inside and outside but could not find it...
So inconvenient ...
Anyone know where should that be normally?

My trailer is creekside 23bhs, the porch light is the black bar under the awning on the top...

I lost the contact information from my dealer and could not find it anywhere on the manual...

Hopefully you experienced guys might know...
Thanks in advance and sorry for this really silly question...
