several thoughts..
either headlights are shorted, or drawing way too much power, so that the voltage drops so low, the coil can no longer produce enough spark and it dies.
This could also mean the alternator is NOT working and the battery barely has enough charge to barely run the coil at about 2 to 3 amps of load.. as soon as the 10 amps of lights come on, the battery gives up the ghost and the engine dies.
if its 12 volts, jump with from a car with good cables and retest... the car supplying the extra power should fix the problem... and the car if running, will try to charge up your mostly dead battery or provide enough power to run it. this will eliminate a low/ nearly dead battery.
also could be a very bad connection between battery and system .. in the run circuit... so the add on of the headlights will lower the voltage going to the coil, but not affect the starting circuit as it routes differently from the ignition switch to the starter solenoid.. so on that premise, look at the ignition switch down to the coil... assuming the crank circuit runs through the ig switch and works well.
I am assuming if it cranks good, then the battery must be sound.

Today's Featured Article - The Rescue of a Fordson F - by Anthony West. Introduction I live in the UK and have for many years restored Fordson tractors (in the main model N's).

At one time I had seven restored examples which were shown and used in ploughing matches. As most restorers, I have a number of war stories I can relate on a range of topics that may help other like minded and interested people. Perhaps my first p
