TORRANCE, CA — August 27, 2001 — LEDtronics® announces sunlight-visible AUT-1157 Tail/Brake LED Lamps that are designed to replace incandescent 1157 bulbs in combination tail/brake signals in most cars, motorcycles, forklifts, ATVs and trailers. Having nearly twice as many LEDs as competitive lamps, the AUT-1157 LED lamps feature 24 Super Red (633nm) discrete LEDs that are scientifically configured to maximize brightness and to fill the entire light fixture. Eighteen LEDs direct light straight through the vehicle's fixture. Additionally, six LEDs are arranged perpendicular to the lamp base in order to radiate light onto the light fixture's reflector and illuminate the entire surface of the fixture. Total light output is 100 end footcandles.

Integrating solid-state electronics with advanced LED technology, LEDtronics' AUT-1157 LED lamps offer automotive applications years of reliable performance, which represents potentially millions of dollars in reduced repairs and ancillary costs. Due to faster turn-on times than conventional incandescent signal lamps, AUT-1157 LED lamps promote safe driving by increasing the amount of response time available for motorists. AUT-1157 LED lamps operate 0.2 seconds quicker than incandescents. That's an extra 19 feet of response time at 65 mph for the trailing vehicle. [Distance traveled = (mph)(5280 feet/mile)(1/3600 hour/sec)(0.2 sec.)] The results? Less rear-end collisions, which are the second most frequent type automotive accidents. The AUT-1157 LED lamps advantages over equivalent incandescents are not limited to automotive repairs and accidents, but extend to collateral issues such as property damage claims, productivity losses, medical expenses, legal and court costs, etc. . . . AUT-1157 LEDs offer economic savings far greater than offered by the price of the incandescent bulb. LEDtronics' 1157 automotive LED bulbs feature industry-standard 15mm index dual-contact bayonet bases that are plug-compatible with most major automotive manufacturers' 12-Volt DC systems.* Other voltages available are 24V, 28V, 36V and 48V. AUT-1157 LED lamps replace incandescent lamps numbered 1157, 2057 and European P21/15W bulbs. AUT-1157 LEDs feature built-in current-limiting resistors and polarity-protection diodes to assure that circuit modifications are not required.

LED lamps' low-current, high-efficiency operation uses on 10% - 20% of the power consumed by incandescents. Not only are AUT-1157 LED lamps energy friendly, but the reduced power consumption presents both the manufacturer and vehicle owner with a number of potential cost savings and design options such as reducing the size of the alternator, using light gauge wire for the electrical system and improving fuel consumption due to less weight and engine load. Additionally, LED lamps produce little or no heat resulting in lighted panels that are cool-to-the-touch unlike those lit by incandescent lamps. A typical LED lamp provides an intense beam of colored light. The intensity and wavelength remain stable over the lamp's lifetime of 100,000-plus hours(That's 30-50 times longer than incandescent bulbs!).

Founded in 1983, LEDtronics leads where others only follow when it comes to designing, manufacturing and packaging state-of-the-art LEDs to meet the world's constantly changing lighting needs. Our inventive product line encompasses an array of direct incandescent lamp replacement Based LED Lamps, low-cost snap-in and relampable Panel Mount LED Lamps and holders, high intensity sunlight-visible Discrete LEDs, PCB LEDs circuit board status indicators, surface mount diodes SMT LEDs, full-spectrum rainbow RGB LEDs and Infra-Red (IR) LEDs. Prices for AUT-1157 LED lamps range from $48.50 each in quantity of 1. Samples are available to qualified customers.
