L.E.D. bulbs question.
Hi,
I recently purchased the L.E.D. bulbs for my turnsignals and corner markers.
I can run the back L.E.D.s and the corner markers with no problem. Although the blink rate is considerably faster on the turnsignals, they all work.
However, when I install and run the front turnsignal L.E.D.s together with the back I get no blinking (all the right lights are on, just no blinking) and a buzzing noise. If I replace the stock bulb the blinking resumes.
I am thinking the L.E.D.s are not causing enough "resistance" (I hope that is the right term) to make the flasher cycle?
Anybody have any experience, educated opinions, or ideas?
Thanks,

I am trying to find a heavier duty flasher to try....Any ideas on who (besides Ford) might have one?
I have tried Kragen, Auto Zone, and the locals....no luck.
Any body have a west coast or internet solution?

Here is what you need

Scroll down to the bottom and look at the load equalizers

You will need 1 equalizer for every bulb that is in the flash circuit.
If you replace both front and rear flashing bulbs you will need 4 equalizers to correct the resistance in the circuit.
If you know your electronics you can build them with the correct resistor.

Try replacing the stock or aftermarket thermal flasher with an electronic one that should cure the problem.

Do you have any sources for an electronic flasher for a 2001 Super Duty?
I have not been able to find one, after much searching.
I can find stock ones but nothing else.
The key seems te be 99.5 and newer are hard to find anything but stock.

Hey guys,
At the seventh auto parts store I searched, I finally found a guy who knew how to special order me a variable load flasher for my 2001.
Thanks for all the advice,

L.E.D. bulbs question.
Turn signals haven't changed since the 40's. But with LED's that will change soon. The problem is current or load on the relay that turns off and on the lights. When the current flows, it pulls current thru a bi-metal connection and the heat caused will break the link and allow it to cool and connect again. The load and voltage will vary the rate of "blink". The LED's have very low current draw and thus with one bulb replaced the blink rate changed. With all the bulds replaced, it's just like no lights installed. This rate change was also a quick way to tell that you have a indicator blown out.
One solve if your going to replace all the lights with LED's is to replace the flasher relay with a solid state unit and adjust the rate. For replacing a rear set or front set, a current load is needed.
