LED tail lights. Front indicators flash 1/2 speed
« on: August 14, 2019, 08:41:17 PM »
I installed LED tail lights and they work great. The only problem is the front indicators flash at half the pace of the rear. The globes in the front are still standard . So do I have to change the front globes out to LED and or is it the flasher can ?
Once again thanks for your help.

I am by no means an expert on electricals, but I do know that LEDs work instantaneously as apposed to the old incandescent globes, giving the appearance of a delayed response, ( this is very obvious following an old car with a new trailer indicating )
It's just the nature of new verses old, don't know if there is a solution other than updating the front lights too,  Andrew..,

Easy task to swap out the fronts for LEDs but then it's 99% likely you'll need to swap the flasher can for an LED compatible unit.

I'm not an expert on electrickery either, but in my experience of fitting LEDs to bikes and cars, as long as you have at least one globe in your circuit it will work OK.
If you go to all LEDs you have to fit a LED flasher unit.
When I fitted them to one of my bikes, I had a globe wired into the circuit and mounted under the seat to provide the resistance needed....looked a bit strange when people saw my backside flashing at them at night.   :lol:

you will need leds front and back and a LED flasher, the current draw is less so it confuses the flasher can.

Just make sure you get a flasher with a decent simulated click noise - some of them are god-awful...

I did the LED mod just last week and noticed the same thing, the fronts flicker at a reduced rate. Will have to get LEDs for the front now by the looks of it.

I bought these ones and they're pretty good. The blinker sound is great, at least I can hear it now, not like the old one.

I had a look at mine today - LED kit in the back and standard globes in the front - and they flash both ends in absolute unison. When I put the LED kit in the rear it came with an LED flasher unit which I installed and removed the original one.

My front indicators also do the same thing. I tried LED lights in the front but they didn't work at all. So I live with half speed indicators on the front!

I finally got time to get around to getting a couple of LED globes for the front..
When I put the parking llights on all is fine then when I put the indicator on both front indicators
Flash like hazard lights  only good thing so far is they flash the same rate as the back.

Sounds like a Isolator LED Indicator Bulb would help.

Thanks very much for that link 289 vert. I've been accepting this issue for years on my 65.
As electrics are not my thing where is that isolator installed and what does it do?

It takes the place of the single turn signal bulb in the dash of cars with the Falcon style dash.
I'm guessing that it stops the indicators on one side, backfeeding the other side.
Get in touch with Gary at Vintage Leds ...His advice is free, and he doesn't mind helping.
His products are the best of there type available IMHO

I put LED's in my Lotus and had the same problem.

The old flasher cans rely on the resistance in the bulbs for it to work correctly.  LED's have very little resistance.

Solution, Adjustable LED Flasher Relay.  $6.40 on ebay.  It works as advertised and you can adjust the flash frequency.

Thanks pete,

Couple more questions.

Is there 2 flashers in a 65 mustang? Because I already replaced a flasher when I put the rear led lights in. They work fine. It's the front bulbs that only flash at half speed. Or the front bulbs don't work normally with a led flasher?

Mine doesn't have 2 flasher units.

The resistance needed for the old flasher cans to operate correctly is the sum of the front, rear and dash indicator lights.

If you put LED's in any one of them it is likely to change the speed of the pulse.

The adjustable flasher works because that you can turn the speed knob until the system works at the speed you want.

I can't imagine that your rears would flash at a different speed to your fronts?

Pete
