Fixing to inside of fridge

Before you go screwing something onto the inside of the fridge - what's the Make/Model and what have you attempted so far to get the built-in light working again?

Wouldn’t the battery drain quickly in the cold?

Of you are going down the route is an attachment then something like this may be better.

They have a plate that sticks onto the surface and the light can be removed to replace the batteries. It would be much safer than putting a screw into the unknown, and risks involved to the sealed unit and/or hitting a wire or some component behind the fridge wall.

I know that one in the link is out of stock right now, but there are other similar brands with the plate.

Would you not just replace the bulb?
