The LED taillight conversions were designed to replace the 1157 incandescent lamp in 1971 through 1974, Pre-L and L-Model Pantera taillight housings. The LED Arrays are available by function and color. The brake sections are always red, the turn signal sections can be ambler or red. The LED Arrays are modular by design and can be ordered in any combination. The electronics is different between the brake section and turn signal section by function, so the LED Arrays must be used in the proper section. The amber or red turn signal functions as a 1157 incandescent lamp with the exception when reverse light is "on" both turn signals flash or strobe at 3 times a second in order to alert others. If this feature is not desired then it is disabled by not connecting 1 wire.
