By adding these G.I. bulbs, you enhance the backglass art and give that overall general light.
 
Behind the glass you can use the less ’ghosting’ bulbs because they stay ‘on’ at all times.
 
Non-polarized means they will work placed in the socket in either direction.
Older &  less expensive bulbs would have to be placed in the socket in one direction.
 
They are high quality 5050 SMD bulbs. Not the weaker 3528 used by many pinball led companies.
