No ohm meter, no problem.
Get following;
1) 9 volt battery (smoke detector)
2) flash light battery
3) 3 strands of wire
Attached wire from battery positive to bulb ground
then attach wire from bulb positive to one post of the switch then attach wire from other post of switch to battery negative.
Now turn switch on to see if light bulbs lights.
