The D1WY-15A434-LSM LED Side Marker Light Adapter kit is required when the C9WY-13A366-AL or the TS-400 Sequential controller is installed with LED front turn signal and rear LED side marker bulbs on 1971 Cougars and other Ford vehicles with two rear side marker lights. An adapter is required for each rear side marker light (2 total). This adapter solves the problem where the side marker voltage feeds back through the front turn signal bulb when the running lights or headlights are turned on. When this happens all the rear bulbs may flash together or it may trigger the opposite side to turn on. It solves this problem by providing a direct ground path for each side marker light. Two red LED bulbs are included. These adapters maintain the original Ford factory function of the side maker lights:
1. light up solid when the headlights or parking lights are on;
2. flash in unison with the front turn signal when the headlights or parking lights are off;
3. flash alternating with the front turn signal when the headlights or parking lights on.
WARRANTY: The adapter kit is covered by a limited warranty for two years after purchase. Should the unit fail during this warranty period, it will be repaired or replaced upon prepaid return to your dealer. This limited warranty does not include repair of damage to the unit resulting from accident, disaster, misuse, abuse, unauthorized modifications or any use beyond normal operating conditions. This warranty excludes any coverage for incidental or consequential damages.
1971 Cougar owners: This is one of the components that you'll need in order to use our Plasma LED taillight bulbs in your car with the sequential turn signal system.
1972-1973 Cougar owners: This component is not needed, as the rear markers are not part of the sequential system on 72 & 73 Cougar.
