Default 1157 LED bulbs
I installed 1157 LED bulbs in my 1978 vette, the signal and brake lights worked great until I turned on my head lights, then they stopped working.
What did I do wrong.

google "1157 led problems" and you will discover in some cases they recommend a load resistor such as these

I had to add load resistors to my front LED 1157s to get them to work. Already had the heavy duty flasher but still would not flash without adding the resistors.

You generally only need the load resistors for the turn signals. Headlights shouldn't cause that.
