Default Replacing tail side marker with led and it wont stobe ?

Hi there
i wanted to add some cool led strobe blinker lights to my tail to match my front side maker leds so they would strobe. Problem is the led light only lights up doesn't strobe at all but i put the oem {stock} bulb in it works fine what is going on ? IT also works fine with harzard lights on.

Can i please get some support here thank you..

with the different resistance of the LED and the Regular bulb, i believe that you need to change the Flasher for the turnsignal

Hmmm..first, If by strobes, you mean like real strobes, I don't think that is legal (something about only police/fire dept can have colored strobes, construction vehicles are allowed clear strobes in the corners.)

If you are talking about LED'* in place of the turn signal bulbs, then you're ok and the problem you are describing is perfectly normal. They either blink at a super-fast rate or they don't blink at all.

Old fix was to ballast down the circuit with 10 Watt resistors. (The stock flasher relay needs a load in the circuit to work)

New fix is to replace the standard flasher relay with a solid-state relay (auto parts store, about $8.00) which uses a timer circuit inside and doesn't care about the load it'* driving. That will restore the blink rate to normal when using LED bulbs in the turn signal circuit.

I might need someone else to translate that into normal English. But *if* I understand your statement:

You put the regular Incandescent bulbs back into the circuits and they work correctly.
Then you put the LED bulbs into the circuit and they do not work, except when the 4-way flasher circuit is turned on.
Finally, you put the incandescent bulbs back in and it works again.

Is that correct?

What I think you are missing is that the stock Flasher relay needs a load in order to operate. The quantity of Incandescent bulbs in the circuit add up to the total load. On a car it can be as low as 3 bulbs or as high as 5 in the turn signal circuit ( 2 front turn signal bulbs, two rear turn signal bulbs, AND one in the instrument panel.)

An LED turn signal bulb draws far less current than the incandescent bulb it is replacing. Change enough of them and the load the flasher relay sees is too small for it to operate and make them blink (sometimes the come on solid, other times they will not light at all.)

The reason the hazard lights still work is because it is running BOTH sets of turn signals at the same time, and just happens to see the combined load as being high enough to operate the flasher relay.

So, I'll state it again. The solution to your problem is either add enough load to the turn signal circuits to make the flasher work, or replace the flasher with a solid state one that works regardless of the load.

Cut one of the wires going to each bulb and put in a 35 ohm 10 watt resistor in series for each 194 bulb, and a 5 ohm 40 watt resistor in series with each 1197 bulb

OR

Go to an auto parts store and get a timer type flasher relay.


option 2 is much cheaper and easier

Walk or drive to an Autozone or Advance, and ask the person behind the counter for an Electronic LED flasher

You just find where the turn signal relays are and replace them.
