Beacon-Lite
HE spark plug of the future—TODAY!
You can see it FIRE! Its visible spark
is the X-Ray of your engine! IT TELLS
YOU INSTANTLY whether your carbure-
tion is right or wrong!
IT INSTANTLY INFORMS YOU whether
your ignition system is operating correctly.
It lets you SEE exactly what is going on
INSIDE your motor!
Just raise your motor’s hood—and the color
of the flash in the spark plug’s Transparent
“Opalite Core” shows how your engine is
firing.
A yellow flash means too rich a mixture—it
warns you to cut down on your gas.
A dim flash in any particular plug denotes
valve trouble, loss of compression, faulty dis
tributor or defective coil.
A PALE BLUE FLASH signifies perfect
combustion.

Heacon-Lite Spark Ping!
Opalite is a vitreous material—seven times MORE impervious
to an electric current than porcelain. It is far, far tougher. It
can stand far higher temperatures. It is TRANSPARENT.
That’s why you can see how your engine is FIRING INSIDE.
Opalite REFLECTS the flash from the compression cham
bers. No porcelain spark plug in the world can do this.
Furthermore, Opalite DELIVERS 100 per cent of the firing power to spark
points. It does so because it has a 55,000 volt insulating resistance. Porcel
ain has only 8000 volts resistance, while practically all gas ignition systems
deliver 18,000 volts to the outer end of the spark piug. Beacon-Lite delivers
ALL the 18,000 volts—porcelain only 45 per cent.
MORE MILEAGE AT LESS COST

I T that's only part of Beacon-Lite’s invaluable service. The Beacon-
Lite plugs will NOT absorb oil or carbon or become foul.
It means no more leaky short circuited plugs. Its insulation is SEVEN
TIMES more resistant than the porcelain plug.
It delivers TWO AND ONE QUARTER times MORE current to your spark
points than a porcelain spark plug.
It is NOT affected by temperature changes.
These things mean a FATTER spark—a fat spark and EXACT CARBUR-
ATION mean a BIG SAVING in gasoline—a marked INCREASE IN MILE
AGE AT LESS COST.
Beacon-Lite PREVENTS the formation of CARBON—the destroyer of pow
er and the wrecker of good motors. It eliminates waste. It produces the
maximum of power. It transforms even a jerky, noisy motor into a powerful
smooth running unit—and one that can lx* kept in prime operating order
merely by an occasional glance at Beacon-Lite's tell-tale FLASH, visible the
second you lift your auto’s hood.
s
Powerful sparks mean maximum power; no carbon; no oil diluted by un
burned gas. Weak sparks mean inefficient motors, waste and costly wear.
SEE BEACON-LITE IN ACTUAL OPERATION
OU don’t have to buy Beacon-Lite Spark Plugs on faith. Under our un
limited guarantee you can put them actually to work on your OWN
car. Simply write to us, or call on any of the dealers mentioned be
low. “Plug them in” and watch for startling results.
The first thing you will have to do is to CUT DOWN YOUR GAS MIXTURE
anywhere from 15 per cent to 30 per cent. The instant your motor turns
over Beacon-Lite will flash “yellow”- because the leanest mixture you can
use efficiently with the old-fashioned porcelain plugs is TOO RICH when
Beacon-Lite plugs replace them. One of Beacon-Lite’s jobs is to “make four
gallons give you the mileage of five.”
Watch the flash—it will rapidly change to blue—as the big hot spark clears
away abrasive carbon and your motor settles down to clean, fast, powerful
work. Try this TODAY—under our guarantee of absolute satisfaction.
He can think of nothing fairer nor squarer. Can you ?
