The result is a modern dual-color effect! Also included with the kit is a pair of 194 HP3 cool white bulbs to replace the factory amber sidemarker bulb. This is one of the best ways to easily add styling to the S550. Brightness. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare. Reduced Load. While LED upgrades do have a lower power draw compared to you factory bulb, you do not need to do any wiring or install resistors- just replace your factory bulbs. Due to the circuit design of the S550 Mustang, you do not need resistors to slow down the blinking speed. Your indicator in the dash will blink at a different rate, but your exterior turn signals will always blink at the standard speed.
