What is the best replacement headlight switch for the 69/70 Shelby on the market today?
Tried a standard (per the advice of a "Shelby expert" I now used to hold in high regard), but the ride home from a movie shoot this evening and the switch overheated after 20 minutes and non LED or Halogen headlights......Flashed on and off like I was undercover and trying to pull someone over :o :o :o
Assuming a C9ZZ-11654-A (or B) switch would be correct ? ? ?
Anyone make an excellent reproduction that actually works?
Thanks in advance

I would suggest that you check out the alternator, voltage regulator, grounds and then the headlight relay.
If it is the relay order a 1969 Mustang with four headlamps.
Pretty much any auto part store will have one.
Or put in a harness with a relay.
Daniel Stern has the best quality relay harnesse, available in a kit form, or totally assembled.
He also carries all the H-4 lighting upgrades one could ever wish for.

All of these suggestions are relevant, thank you, nothing else was in your response. While you meant well, historically, your posts have been off topic, and just plain wrong, you really should refrain from google searching or using A.I. for your responses. Perhaps refrain from responding to my posts and threads would be best.
As a response though, all have been carefully and thoroughly checked, tested, and are all fine,with the cause of my original problem (no dash lights) being found to be a bad (cracked) rheostat in the original Ford headlight switch, which is why I specifically asked about the best headlight switch to replace my current, and substandard, freshly changed unit.
Perhaps someone else has hands on experience and will respond more competently than you did.

If you could find a NOS original that would be the best option. I found mine on eBay but that was 10 years ago.

I'm thinking I have one somewhere, but could not find it yesterday morning before I left, which is why I made the post to start this thread, both to see what else is out there, and confirm the factory part number so I can dig through my countless boxes of small NOS bits and pieces.

Just a follow up, found the box, had the old, original headlight switch from 1584 in it, grabbed a C9ZZ-11654-A off Ebay, hope it works.
