***I've replaced all of mine with LED's but am not to the point of installing a Battery in my car to verify operation. The charge light you say needs to pass current both ways to work makes sense... I hadn't thought of that but can you explain why the courtesy lights need to and what's your idea to fix the problem???

I've got a handful of appropriately-colored LEDs to replace the all-glass 2721 bulbs - e.g. oil pressure/fuel/brake warning, fan/heater controls, etc. Think they were 10 for a buck fifty... LOL.

***I just used warm white bulbs here as all of the indicators have colored lenses.

One issue I've encountered is that the LEDs - actually, just one side - for the flasher/indicator repeaters in the tach behave oddly. The right side flashes with the hazard switch, and also flashes on the "off" part of the cycle for the left indicator circuit.

***I ran across a thread awhile back that I think addresses this issue. The relay gets replaced with an electronic type (for use with LED turn signal bulbs) then the ground on the back of the tach is piggy backed to the indicator bulbs... problem is I don't know if he was using LEDs for the indicator lamps so now I'm really stumped. I'm wondering if a resistor placed between the two would correct this???

I probably haven't help a damn bit so I'll be watching this thread for a solution.
