PAGE FOUR ÜKESHAÄ OUTLOOK, OBEN HAU, OKEGON FRIDAY, JUNE Beacon HE spark phig 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. T SPARK PLUG--- • 1 • . • * You see it FIRE!

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, lurthermore, 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 plug. Beacon-Lite delivers ALL the 18.000 volts—porcelain only 45 per cent. MORE MILEAGE AT LESS COST UT 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 AN I) 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- .',mvan a BIG HAVING in gasoline—a marked INCREASE IN MILE­ AGE AT LESS COST. Powerful sparks mean maximum power; no carbon; no oil diluted by un­ burned gas. Weak sparks mean inefficient motors, waste and costly wear.
