Hello, Quick question on non-working r2 drop in

[for]

I dropped my L2R :shakehead long time ago and it stopped working, I didn't want to buy another drop in so I stopped using it. I'm a noob and don't know how its connected. I recently check it out cuz I was gonna just replace it with a brighter p60 drop in sku.11836, using 2 14500 batteries. I found out that by touching these places in pic it lights

I want to know if you guys know a quick easy fix based on what I showed in pic?

If the solder didn't take all the substrate with it when it came loose, you may be able to just re solder the wire down, just don't overheat the led if you attempt to do so.
