So you can just plug a small LED into the bulb holder, and that's it. No need for a current-limiting resistor, as in most LED circuits? I guess the current limiting is in the flasher.
I would like to have brighter brake lights on my Duetto, but am less concerned with brighter tail and turn signal lights (I seldom drive the Duetto after dark and no one pays attention to turn signals here anyways).
Since the Duetto groups the brake and tail lights on a dual-filament, 1157 bulb, while the turn signal is by itself on a single-filament 1156, a short cut would be to just swap the 1157's for LED bulbs. That way, you don't get into adding resistors in parallel with the LED exterior bulbs, or substituting an LED for the indicator bulb.

How does that dash indicator come out? From the front or the back? I've never pulled one of the little jeweled indicators, and have several that need work...

Below is my indicator rig: I used a cut bit of a plastic tie wrap as a center divider, and trimmed the LED legs. That's the whole process!

Also, will the CF13 JL-2 flasher support a mix of LED bulbs at the rear and incandescents at the front (or vice versa)? Or are you saying that all bulbs (including the indicator) need to be LED?

Do you have one of papajamma's circuit schematics for your Spider?
On it, for my 1976 Spider the 3-pin flasher is marked as "C" going to the turn signal switch & e-flasher switch (which sources a "flashing" 12 VDC for the lamps), "R" goes to the indicator on the dash, and "+" to a fused 12VDC.
The cheap CF13 JL-2 flasher for LED loads I used connects with it's "B" terminal where "+" is, "L" on the flasher goes to the "C" connection wire, and (this is the tricky part!!) the flasher's "E" connection goes to the "R" wire... but the flasher draws so little current on "E" that you must use an LED, oriented correctly (+) side to the flasher, (-) to the dash indicator, in place of an incandescent lamp.
I used a 10mA green LED in my indicator lamp holder, and it lights nicely.

I just went down the path of LUYED turn signals in my '72. I love the light output, but my can flasher wouldn't flash them. So I bought one of the orange AUDEW flashers and ... it won't flash them. They are always on.
Now, some previous owner had rigged the car to use a two-prong flasher instead of three. I haven't completely traced that down yet, but there's a bundle of wires at the output of the flasher, so I have a guess at how it's working (the dash indicator gets lit up when there's draw from either side of the turn signals). I don't know if the dash indicator is LED or incandescent. I'm contemplating going back to a 3-prong unit ... but I'm also wondering if adjusting the flash rate screw on the AUDEW might help.
Thoughts/words of wisdom?

Roundtail LED upgrade
Just the info I needed to help upgrade my roundtail. I attempted to do this years ago but LED bulbs available at the time were dimmer than stock. I ordered bulbs Friday. Crazy amazon delivered them free SUNDAY am. After a few glitches (broken ground wire in housing, re-broken lens mounts) I got things ironed out. Painted the interior of the sample housing white. Turn signal flashes too quickly so I have ordered two resistors to fix that. Here are links I used on amazon. Some of those links from earlier upgrades in this thread no longer exist.

|Sfizio||I hate when that happens! Hey Nick, also check that you did not accidentally blow a fuse. I did when I was changing out bulbs for LEDs.|

|ntvnyer||I did brake/tail lights and the reverse lights. I avoided the blinkers because of the flasher issues. My grounds are good, I cleaned them up while I had the taillight assemblies out. I think my problem will turn out to be disturbed wiring under the dash. I am lucky in that the wiring on my car is not chopped up, but that also means that I am dealing wil brittle old stuff. I will post a solution when I find one.|
