Another strange turn signal issue
(04-08-2019, 12:09 PM)Rmach1 Wrote: Can anyone tell me if there are two flashers or one for turn signals and one for emergency?

Thanks all!!
I have another issue.. no brake lights but when I use turn signal, two bulbs on each side come on in the tail lights. My first Mach 1 so I’m not sure how many lights should blink when turn signal is flashing. I thought just the outside one and inside is the brake.. can someone help with what light come on and when? Thanks all!!!
Both lights on each side should have running lights and brake lights/turn signals on. The third bulb is backup lights. You probably have a bad grounding issue back there, quite common on 7123's. Bad grounds at contacts with bulb sockets at the spade leads and corroded sockets.

Let me check your shorts!

Something to keep in mind when replacing front and rear turn signal lamps with LED's.  You need two LED flashers.

Ahh, had no idea.. thanks!!
There are few types out there. Some with 3 or more connections.
These are plug&play. They fit our connectors with zero change.

From my own experience only, the electronic flasher Fabrice is showing did not work with the better quality LED or SMD bulbs I bought from HiPo Parts. I required 2 LED flashers, one for turn, one for hazard, that are polarity sensitive and GROUNDED. In my case I needed to switch the wires in the connector in the  glovebox. Thank you Ford for reversing the wires!! I just made up a couple of short jumper wires to fix that issue.
Go to www.hipoparts.com and buy the good stuff.
Just my opinion,

I learn something new every day!

Ordered LEDs on Ebay, 5 dollars the dozen for the exact same ones I see on this site (they all come from China anyway). Ordered also in different quality/fittings for the inside, in amber and white for markers and reds in 2 fittings for the the turn lights/tail. The 2 flashers out, new in. Done.

I will not argue if they are crap or excellent for each types I have till I have drived the car for a long time. So far each time I use a switch they do and look fine. May they fail, just like I did with the incandescent ones, i'll replace. Since there is no heat I could feel, I suppose it's gonna take a significant amount of lighting hours before they fail.
The original Ford fitting is on both my cars 2 fittings for the flashers and both are fused lines.

Again, old out, new in, done. For once, no extra work, liked that! Smile

They offer the same one, in case you do not have 100% LED or have blinking issues. As I still have the incandescent bulbs for the turn lights in dashboard. Fits my needs.

Is this the one you refer to with the additional ground wire? Sounds like its indeed more suitable if you are 100% LED

Good to know if I ever update the dashboards ones.
