I have a 74 Swinger. it's beautiful. It's dashboard has a round 'fasten seat belt' warning light, located beneath the fuel gauge.

I have noticed that on some 74 and 75 Custom/SE models, there's another...something located next to this light, beneath the temp gauge. Whatever it is, my 74 Swinger doesn't have it.

Here's a link to a photo of one.

What is this? another warning light? or something else?

That would be the EGR warning light. Look under the hood. There is a rubber covered thingy that connects the lower part of the speedo cable to a shorter upper part. I believe it is some sort of mileage counter that warns that it is time to check the egr. I just unplugged the wires on mine. My egr is working fine and that little dash light is really bright red and kind of annoying.

hmm. interesting, all these archaic 70's safety features!

74DartSwinger is absolutely right;
the EGR light was run by a little clockwork mechanism off the speedometer cable that didn't "know" anything about the EGR, it was just a reminder to check it every so many thousand miles. Normally, one could use an allen wrench to reset the clockwork for another round.

I combined the EGR light with the Fuel Pacer control to make a Yee-Haw light that congradulates the driver for stomping on it. The hard part was the legend - a bulb overheated it, so I made a bright LED replacement for the bulb.

you guys seem to know all about these lights. what about the light next to it; the fasten seat belt light? does the light work on your car? do you have that Seatbelt/interlock safety function working? or does the light just not work?

Yep, and if in working order has an accompanying buzzer that goes on for 5 seconds until you belt in, or it just goes out via timer... Goes with the interlock system (sensor in the seat meshing) on pre-75 cars...after 75 it may have a system tied to the seatbelt that just cuts out the buzzer...


-D.Idiot

so if the interlock system has been disabled, the light on the dash won't work?

i have the buzzer working - it's just the key in the ignition, when the door's opened. when the key's in the ignition and the door's shut, it doesn't buzz at all...

I am getting ready to install some of those cool hard back buckets from a 67 cuda in place of the bench seat. I am pretty sure that the buzzer is just straight connected through the belts not a seat sensor. But I guess I will find out the truth to that . I'll let you know if I remember!
