Replacement flasher for high current draw

Take the halogen out and put a normal bulb back in.

1. Your wiring is not designed for the load
2. Your wiring is still not designed for the load
3. Your lens will not like the amount of heat it generates
4. What is the brightness difference between running light and brake, it will not be
correct, every halogen tail I've seen has an overly bright running light
5. Halogens are much slower to come to full brightness than incandescent, Do you really
want brake lights that are slow to turn on
6. If halogen technology made sense for brake lights wouldn't at least one automaker
have installed them from the factory
7. Just because an auto magazine says to do it doesn't make it a good idea.

Are the taillights on that car round approx 5" in diameter? I remember reading that one of the pre 65 darts could accept a round led trailer light with almost no modification to either the car or the light. That would be a much much better solution than halogen bulbs.
