I just replaced one of my taillights on my '66 C-10 stepside. It works fine except that when the brakes are on and the turn signal is on, it won't blink from high to low, instead it blinks on and off. Also, when the headlights are on and I press the brake pedal, it cuts off, and when the headlights are on and the turn signal is on, it blinks on and off, not high to low like the old one did. What's going on with it and what can I do to fix it? Any help is much appreciated.
