Effective gadgets for side visibility?

Hi Taras or anyone else who might know.

I broke the battery holders on my ledus (probably in a crash I walked away from). One is lost entirely and the other has lost one of the side clips.

Reckon I can replace them with anything like this and it'll work again with a little solder?

One of mine has broken too in the winter weather, keep me updated, they were shoddy anyway.
