Broken Tank Light (Aqualantis)

[thedoors27]

Hi everyone! Recently been given a tank, needs a good clean etc but the light doesn't appear to work. It's a tube light and so far I've replaced the starter but still no luck. The on and off switch on the actual light feels broken, there's no click etc and the screws are rusted/rounded off so I can't open the metal casing! All it says is on it is "aqaulantis". Does anyone know what model it is and is it worth me replacing pieces if I can somehow remove the screws or just replace the whole unit?

Hopefully the attached pictures work!

Any advice would be grand.

Maybe you can bypass the switch and just tape the wire. If you use a timer you don't need an on/off switch.
