The lamp had received a new entity texture but the item texture remained the same as the old lamp texture. This is a fix for that.

Announcement!
This issue is fixed in Factorio 0.15.x :)

Update 1.0.3:
Updated to work with Factorio 0.14.x if so desired.

Update 1.0.2:
Fixed the new lamp texture not showing in the electric network info.
