Here is my strategy for this one, it usually works (unless you’re unlucky) without using tools.

Make some strings of at least 6 lights until you have one that will clear vertically, then use that light in a string to clear one of the four locked lights at the top. Continue stringing and breaking those 4 until one of those 4 has a horizontal line. If you can get it lined up right then you’ll be able to use a vertical light below to hit the horizontal at the top and clear out all 4 at once.

It takes practice to get faster at it, but it comes with just playing this puzzle a lot.
