LED conversion '99 Lincoln Sign In

I am not a professional...I am a DIY senior. I want to convert my '99 Lincoln Continental from the OEM halogens to LEDs. I previously converted my '05 Ford van by swapping out the flasher control relay and all LEDs worked perfectly. Since the Lincoln flasher unit is buried under the dash, I am trying to make the conversion using LED load resistors on all lines for the turn signals wires, but, even with resistors installed, I am getting hyper-flash. At first the blinkers worked until the parking lights/headlignts were turned on. Then they went to hyper-flash. I have tried using double resistors, using 6 Ohm and then 8 Ohm resistors, and even adding a resistor diode to the non-flashing wire to my turn signals. I also tried a plug-and-play ready made wiring connector that used a resistor on both the non-blinking and blinking wires. All of these attempts have failed. In fact, now I even have hyper-flash when the parking lights/headlights are not on!

I finally bit the bullet and dismantled the dash and retrieved the flasher relay but I have not been able to find an electronic replacement. So, can anyone diagnose my problem and how best to correct it? Help, please.

Re: LED conversion '99 Lincoln Sign In

The easy and simplest thing to do is don't mess with them. You already have a hyper-flashing on the other one basically need to use up some watts for waste so why do it?
Opinion side: I needed some for another reason totally: Bright when new but OMG don't last for crap. Water/moisture gets in, they are NOT at bright as when new plus just quit for no reason not finding them very handy at all and quite costly if you don't find some on-line deal.
I'll say - I wanted super bright back up lights for a '97 truck much needed. Took OE bulbs out so no overload of the switch if whatever lies they claim they use do work but need spares assemblies totally if they fail and have twice in two years.


Not so pleased so far see a lot of funky things folks do with them for decorations too that aren't working out in exposure of a vehicle apparently??

Re: LED conversion '99 Lincoln Sign In

If your lights are flashing "hyper fast", that means you have too much resistance, not too little.

Re: LED conversion '99 Lincoln Sign In

Thanks for your reply, Hammer Time...Yes, I realize that, but isn't that exactly what resistors are supposed to do...only allow limited resistance pass to the light?

No, it's not. The flasher is calibrated to flash when it reaches a specific amount of load. More bulbs equal more load and the relay releases sooner and causes faster flashing.

Re: LED conversion '99 Lincoln Sign In

Oh, then all the videos I have watched are all wrong? If your logic is correct, then how do I modify my connection for LED blinkers?

Re: LED conversion '99 Lincoln Sign In

You buy the correct flasher for it.

I explained that wrong

More current flow does cause faster flashing but resisters do not increase the current so you are right in that aspect.

Re: LED conversion '99 Lincoln Sign In

Thanks for hanging in there with me, Hammer Time...I disconnected the OEM flasher (VF80B-17D541-AA) but, as yet, have found no source for the digital replacement. Can you suggest a vendor?

Re: LED conversion '99 Lincoln Sign In

This is giving me a headache: Some with a bulb blown for example will blink/flash faster others slower or not at all. Add a trailer and lights without an interface you are in for a treat you wont like!
Back to the first point - leave it alone unless something is wrong there's enough crap to come along without making more troubles. It's your car have at it?

Re: LED conversion '99 Lincoln Sign In

All I can suggest is go to the manufacturer of the bulb for a matching flasher.

Thanks, I'll give that a try.
