Israeli AMX13s were early hulls hence the single light per side. This is a feature Takom didn’t get right. However the double light is correct for all the later AMX13 s.
To fix this you can make the single light guard with styrene strips like I did with my Heller early AMX13. Or you can use the PE part of the Takom AMX13 /105. Have a look at my build here
