i disagree just add the et difference to your delay and leave on the other bulb. poor mans crossover.
Alot of us carried calculators in 1985. lol That was part of the original reasoning for shading the tree. At least around here. It's not necessarally the driver that makes a good bottom bulb combo. If the car is off enough that conventional adjustments won't get it tight enough, the only recourse is to spend money. A small percentage of drivers have plain dumb luck with this, and get a reputation for being good, when in fact, their car driver fit was luck. Many, many more go home early.
