Sounds like another yarn he told you..........they don't explode when lacking a 200mph wind to cool them.

Old friend of mine (also known for his yarns) told me he had installed
landing lights as headlights on an old car he had.  He said he went to a
parking lot to aim them and they both exploded.  Turns out they need the
200mph wind of flight to keep them cool.
