Here's an ad for a multi-level-marketing scheme for a "high-tech" car headlight, circa 1931. With artwork like this, I'm ready to sign up. I think I just found my next tattoo.
AT LAST! An amazingly queer yet simple invention lifts the curse of night driving from the motoring world. This altogether new discovery called “Perfect-O-Lite,” replaces old glass “bulbs” in your automobile headlights with truly amazing results. Road illumination is instantly doubled yet glare is absolutely banished. Ordinary objects in the road, ruts, animals, obstructions, etc., are made clearly visible at least three times as far. Instead of ordinary “direct” light, this beam is composed entirely of double-reflected or “infused” light. This new kind of light cuts right through the other fellow’s headlights. Even shoots through fog, mist, rain and snow. There is no wiring or installation. No extra upkeep. Banishes the need for glare shields. No wonder concerns like Wallace & Tiernan, N. J., Houston Post-Dispatch, Tex., Columbus, Ohio, Fire Trucks, etc. have already installed Perfect-O-Lite as standard equipment. To prove what this invention will do, the manufacturer now offers a set to every motorist on FREE TEST. Simply mail the coupon promptly for details.
