LED's tend to last than bulbs (I think)

Only if the bulbs are in American cars.

Hi Gary,

The filament lightbulb lifetime increases at the inverse 12th power of
its reduction from the "suggested" operating voltage. This curve
actually holds only for about the first 5 to 10% of voltage depression
(otherwise they would last forever at half power). This is one reason
to buy industrial bulbs (rated at 130V).

The benefit of LEDs is lowered current consumption for the same
brightness (which I will warn is another one of those tricks of the
brain). This is also a deficit for turn signals because it has a
tendency to change the tempo of the flashing which can be mistaken as
multiplexing. :-) The suggested fix is placing a resistor in
parallel to return the circuit current demand to the original level.
