That's a very clever setup.
I would guess the laser is a replacement for the ignition points. The Dino's used two sets of Magnetti Marelli ignition points and they were tricky to set and adjust. They opposed each other in the distributor. I know because I had a Dino and I used to use a flashlight battery and a flashlght bulb set-up on both sets to adjust them simultaneously.
So I think he's now replacing those with a laser.
Smart deal and probably well worth doing especially since these units are placed away from the engine heat.
