My 1987 Mercury Colony Park

[Kodachrome Wolf]

Still haven't looked at the cluster. Need to, but it seems if the car is driven regularly, the issue doesn't occur. Doesn't make a heck of a lot of sense. Seems the illumination/backfeed wackiness only happens after it sits for several days and clears up after the car is driven a bit.


Only thing I've done is swap LEDs into the rest of the back of the car. Swapped the tag lights for warm white LEDs several months prior.




Used the "fancy" built-in resistor type LEDs on the tail/brake/turn bulbs so I could keep the original style 323 flasher working along with the speed control. No problems with that. Even with the built in resistors, it seems some draw must be reduced, as the dash illumination doesn't flicker a touch the way it used to with the original bulbs when I'd hit the brakes. I also used "standard" LED for the reverse light since the originals were considerably dull. Overall I'm pleased with the additional brightness from all the bulbs.

I did LED reverse lights in the Cont trying to get some more out of it when the reverse light switch was jacked and dropping a bunch of voltage. It helped but even now with a good switch thats not losing 3 volts they aren't very bright. I should pull those and see if the reflective coating in the housing even still exists.

Yeah... LED reverse lights on my 93 don't do well (but those are small to begin with) and the LEDs on the Expedition are like rear headlights. Nice and bright. basically 921/912 vs 3156. 3156 has much more headroom to work with.

That looks really good.

not sure what they are on the Conti, its whatever bulb has the same base as an 1156, but the glass part is like half the size of an 1156. It got 1156 replacement LED though since they fit. Just cheap crap tho which is likely not helping.
