The Fox-4 Mustang from the late 90s represented an exciting new approach to Mustang design, and you can make it even more exciting by adding aftermarket 1999-2004 Mustang LED bulbs to your vehicle at various points. With many high quality conversion kits now on the market, there's no need to continue using the bleary, dull, dim, yellowish incandescent bulbs that look like they came off your great-grandfather's 1940s pickup truck.
There are plenty of good reasons to upgrade your Mustang's detail lights to LEDs from incandescents. One of these is visibility. Turn signals, taillights, license plate lights, and reverse lights are all visible to other drivers much farther through the darkness when a bright LED light is shining. Why risk someone banging up your magnificent Pony because they don't notice that you're turning due to a dim blinker?
There are plenty of efficiency gains to be had from 1999-2004 Mustang LED bulbs, too. You can make a small but significant contribution to fuel economy by using them, since they draw only 10% of the power of incandescent bulbs. You're unlikely to need to replace them for a long time, either, since they last for 100,000 hours of continuous use.
Best of all, they make your Mustang look a lot better. LED light is white and clean, with a fresh and crisp look to it, and a lot brighter than incandescent light. That flawless, sparkling shine looks perfect complementing the fierce, stylish lines of a lovingly cared for Mustang.
