Thanks for the input.
I have a high output alternator. I also have a headlight relay kit. I never really thought obout the additional current draw. With the kit it does require an additonal power wire be run to the trunk.
I'm really trying to keep my car "old school". I thought about the LED setup, but I just don't like how it looks. There isn't a fluid flow to them like the incandescent. The LED is too instant on and instant off. Its more of a stair step than a flow. I have seen LED tail lights on new cars and on Mustangs with the LED inserts. I just don't like how it looks.
I have also noticed that with most LED tail lights if someone is not directly behing the car the has them they are harder to see.
Also, the LED setup goes dark between flashes when the tail lights are on. I don't like that either. It should go to the dimmer filiment between flashes when the tail lights are on like the OEM lights do.
Also, the LED doesn't sequence once before staying on during braking.
See how the incancescent look on this Cougar? It has a nice fluid flow to it.

Did you have any issues with yours other than what you said? Where they the Scott Drake ones?
If these are really a bad idea, I may just stick with the stock lights. I do have some GE night hawk bulbs in them. That actually makes a difference. They are the same specs as a regular 1157 but have what GE calls a robust filiment. I have 3157 night hawks in my F150's tail lights and its noticably brighter.
