help with aquarium lighting unit

[ShellBeaumont]

Hello,
I recently bought a second hand aquarium and unfortunately it looks as though the left it out in the rain as the lighting unit looks beyond repair.
I really need some advice about how to rectify this as I really want lighting in my aquarium but I have no idea where to start!! Any help is much appreciated

That look really corroded. I personally wouldn't want to use it. It doesn't look safe. I would say to just get a new hood. Even if the lighting does work to me it looks as though if you used it it would drop bits of rust in to the tank.

I never wanted to use that one as it looks dangerous lol. I was wondering if there Was any way of replacing it? I'm new to this so please forgive me!
