tony. sorry, you must have misunderstood me. i wanted to see the link on how to make your sidemarkers blink when you engage the turn signal. currently, mine does not.

My misunderstanding..

I designed a simple circuit for motorcycle two wire LED turn signals.
The same circuit would work for the side markers lights.

The circuit is nothing more than two diodes and a resistor.
Since the side marker lights are only two wires - 12V & ground this would work for what your trying to do. (side marker lights as running lights & turn signal)

You would basically feed the turn signal lead into one input (diode only lead) and the parking light lead (running light) into the other input. (diode with resistor)
The single output lead would go to the side marker light. plus the ground wire..

All the parts can be acquired from RadioShack. Simple to build, I used heat shrink tubing to enclose the components.
See drawing of the circuit below.
Your biggest challenge would be taping into the turn signal lead for each side.
You would need a total of 4 diodes and 2 resistors. RadioShack part numbers provided.
Hope this helps

Hey Tony,

Thanks for the post. I have done the mod as described by another member that turns the running lights into turn signals. Great SAFETY MOD! However, I lost the "running light" or parking light functionality.

Glad to know a couple RS parts can get it back. I already chopped the wires but the lack of load using LEDs has caused some other "picadillos". I will try the Tony Mod and let you know if there are any ill effects. From looking at the diagram it is for a bike but that should not matter. The lack of load on LEDs causes our cars fits….unless you have a load on the circuit.

It has helped me avoid at least one accident. With LED lighting you can see directly on the side AND at the back of the vehicle too. I had a guy driving in my blind spot, saw the blinker and woke up! Then, I dropped a gear and dumped him!

The safety merits of this mod make it road worthy!

This circuit has been installed on several motorcycles and are still functioning to date, mine included.
I've been running it for several years.

The diodes in this design work as one way switches, the PIV (Peak Inverse Voltage) rating of 50V prevents the voltage from back feeding into each input respectively. The resistor on the parking light input simply dim's the parking/running light.

If you have the fast blinking from the LED's, instead of load resistors I would simply change your Flasher relay to one that supports LED's.
EFL-3 LED Flasher Relay. Simple and doesn't require load resistors on every connection.
I'm not a proponent of putting load resistors across power leads.

THIS IS awesome!

very nice tony.
i'm thinking about doing something similar, but using mini relays.
using the relays will not require any resistor if using LED bulbs.
on top of that, if the running lights are on, the "blinker command" will basically turn them off and on in the blinker pattern.
if the running lights are off, the "blinker command" will turn the lights on and off according to blinker pattern.
this setup is more complicated and will require running a line to the blinker fuse inside the car.

Meir:
The circuit provided below will not require relays.
You can simply change the car's stock flasher relay with the model EFL-3 Flasher relay for LED's.
It plug's right in in place of the stock flasher relay. (It will handle hazards & Blinkers) (3 Pin flasher relay)
3 PIN ELECTRONIC LED FLASHER BLINKER FIX 1157 3157 7443

Circuit explanation:
The diodes act as one way switches of the voltage (out), they block the return of the voltage into the other input lead. (PIV) Peak Inverse Voltage
With a rating of 50 volts PIV, they will not allow the voltage less than 50 volts from returning. Of course the higher the PIV rating, the higher the voltage it will block. 50 volts PIV is more than enough to block 14.5 volts from the car power even at full alternator charging.

To give you an example:
The parking light is on, passing voltage out the resistor & diode to the LED or bulb, the other diode connected to the turn signal lead will NOT allow that parking light voltage to return to the turn signal input.

When the turn signal is engaged, along with the the parking light being on, it will pass the blinker voltage to the LED or bulb.
The diode on the parking light will prevent or block the blinker voltage from returning into the parking light input.

To summarize, they both will pass voltage to the LED or bulb, but block the return of voltage to either of the inputs.

The resistor's role in the parking light is to dim the parking light output, thus when the blinker is engaged, it will illuminate brighter than the parking light.

hope that explains it a little better..

wow. thanks tony!

[tony_fury]

Thanks...

Here's a picture of the components assembled with heat shrink tubing for insulating.
I basically soldered the wires to the ends of the components to allow for connection to the wires on the vehicle.

Hi Tony.
thanks a lot.
you explanation is perfect. in fact i understood it the firs time.
i know a thing or two about diodes and resistors.
the problems are:
1. i have the same relay you mentioned but it doesn't work
maybe a bad one? i sent an email to V-LEDS support. lets see what they say.
2. in your setup, the lights will stay on, and just become brighter when turn signal is activated. using relay it will go on and off just like regular turn signal.


if i can get the relay to work, i do not need to run a wire to the car.
i can use the signal power to run the relay and the LED.

with that said, i love your setup. its great. much more simple to preform.
i never thought of dimming the running light using a resistor.

plus, look what i got in my office drawers:

Meir:
Nice supply,

I do understand your relay concept

I have the EFL-3 in a box and never put it on the car. There was no need since my rear DEPO light have 1156 bulbs for turn signal keeping the load status quo..

I did read an article about a 914 owner that purchased a LED relay and had to reverse engineer it make it work.. Might fit your situation..
Porsche 914 EV Conversion: Installing LED Lights and Fixing the LED Flasher

good luck..
