## Description

SYLVANIA578 41mm Festoon LED White Mini Bulb - Bright White LED - Ideal for Interior Lighting - Map, Dome, Cargo & License Plate (Contains 1 Bulb)

## Features

- Lights Dim Over Time, Replace In Pairs: Your lights are a pair, one is never turned on without the other. If one bulb burns out, the other isn't far behind.
- Instant Illumination: Unlike incandescent bulbs, LEDs illuminate immediately. This "instant-on" technology offers the added safety benefit of giving drivers around you more time to react.
- Superior Performance: Sylvania LEDs are manufactured with bright, long-lasting, SMD LED bulbs and a thermal management system that extends life and increases performance.
- May Require A Load Equalizer For Optimum Performance: To help prevent hyper flashing and bulb out warnings, it is suggested that a load equalizer or resistor be installed. See Sylvania's Load Equalizer product.
- The Sylvania Standard Of Quality: With over 100 years in business, Sylvania is the world leader in automotive lighting for Original Equipment Manufacturers (OEMs) and the aftermarket.
