Flash Light Drill

[LSH]

I would like to know the proper way to use flashlights also.

3. If the Lights were installed in the the butt end and shaft end, would then tracing the Plane Line be correct?

I have an extra dowell that I taped a pen light to the but end and I try to trace through the ball on the back swing.
Is that wrong?

I was going to get a second pen light and tape to the other end of the dowell so I could trace the target line with both ends of the dowell.
Would that be wrong? Should the pen light be positioned near PP#3?
