SUMMARY

The discussion focuses on wiring instructions for converting incandescent bulbs to LED in older cars, specifically from the 1960s. Participants emphasize the importance of using 6-ohm resistors in parallel rather than to ground to ensure proper flasher operation. The need for additional load to facilitate flashing when transitioning from high to low current draw is highlighted. Clarity in communication is also stressed, with suggestions to reformulate questions for better understanding.

PREREQUISITES
  • Basic understanding of automotive electrical systems

TL;DR
How to wire correctly?
On older cars made in the 60's I believe flashers work as I drew it out but dropping resistors sold on Amazon are 6 ohm and it states that they go in parallel not to ground seems to me if you was going from high current draw incandescent bulbs to low draw LED one would put one resistor from lamp positive terminal to ground. Why do I think this it is because when the lamp in back does not burn only front one burns but does not flash seems you need more load to make a flasher work. I also think rather than put one resistor on right and another on left just put one resistor from flasher to ground.

We want to help you - this why we are here. But you have meet us halfway. I cannot understand what you wrote. I could guess I suppose. Please rewrite this question, Then post it in a new question. You can and paste into a new question, then edit to fix the question(s).

The first sentence for example - It really seems to me to be one convoluted sentence that may actually be several sentences. Thanks for understanding.
