The KISS logo is fully lit in what appears to be the switch test.

Sorry mate. should have explained further.

Take a look at the second pic where you can see the backglass and playfield.

The game appears to be in attract mode, with credits switched off in dip settings?.

Now if you look at the kiss bonus lights on the playfield. They are lit in a random way. Also an outlane special light is lit.  Something doesn't look right to me.
