Hey all,

I have an idea in terms of some lighting for my car, however, I need to find a wire that does NOT pulse when the indicators are one, but switches off when the indicators are turned off.

I have checked near the flasher relay and all wires coming into/out of the hazards lights button, but no luck.

I can possibly build something to convert the pulse to a steady signal with a capacitor, resistor and relay, but if there is something there already, it will save me a lot of effort.

I'm guessing there is prob something near the indicator stalk, but not certain.

Anyone? Any thoughts?

What are you trying to do? Indicator and parker in the same light like American cars?

Im with Mohit - what are you trying to do exactly?

I know what you are asking, I cant think of a wire that would be a constant +12V when the indicator is on and not pulse.

Easy! The wire going from the indicator stalk to the flasher unit should be constant, as it needs a solid input before it starts flashing :)

I checked wires coming into the flasher relay, but no cigar.

Basically what Im trying to do is use my rear markers as dual purpose.
I want to connect 2 globes per marker but have the parking light turn off when the indicator turns on.

I have a solution ATM but it involves building a circuit board.

That should be fairly simple, what about a DPDT relay?

Life DPDT will be the same as SPSH. Just two more throw's

Onky, I would say use a 5 pin relay. one with an 87 output and 87a output. (Working this out as I type) You can have one input and two outputs, OR two inputs and one ouput. So, i would have the two inputs being the inputs for the parker/flasher and a common ground.

mmmmm.....pretty sure that'd work......I only have basic relay knowledge so now just trying to work out how the triggers would work...

(someone help me here:P) so I guess you can have a 12V coming into the relay via one pin, but then once you hit the indicators, you'd want that to change over to the indicators circuit making it flash. I gotta do some more reseach BUT I'm positive a normal 5 pin relay will do the trick man

My bad, we are thinking along the same lines just I used the wrong terms...

Anyways, you need 2 relasy that have 2 "out" pins, one for "closed" one for "open". Then wire them so while one is open, the other is closed (parkers on one, indicators on the other).

Life, you dont know so please do not post

The indicators go through the button on the dash for the hazzards then to the indicator and out to the lights. There is no constant power that will stay on when the indicators are flashing unfortunately.

Your best bet would be as Paul stated, a dual pole realy, this will then switch between the 2 poles, only issue you may still get a blink as such as the arm flicks between poles.

You may be able to use another method I have used in the past, use the indicator switch as a switch for the relay, you will need to bugger around with the wiring but if you patch in to the switch wired, the power will go from the switch to the flasher and also to your relay thus keeping it on.

I would have to look at a wiring diagram to see if this will work as some cars have the flasher before the switch (ford as an example) and some after (Mazda as an example) I am not sure on Mits as I have never had to play with them before

Unfortunately, with a flasher running to the relay, it will be turning the relay on and off, therefore making the parker turn on alternately to the indicator.

The circuit i aim to build has a capacitor that charges whilst the flasher is on and supplies power when the flasher is off for a few seconds. Therefore converting the pulsed signal into a constant signal only whilst the indicator is on, which is what i need.

EDIT:

So this is my new idea - function as indicators during the day, and parkers at night!

So the idea is that they will be connected to the indicators and flash as per normal, but when the parkers are turned on, this will cancel out the indicator function.

Here is the wiring schematic which i'm quite positive should work:

I may be reading your schematic wrong,

However you have the relay coil pins connected to the parking lights? Pins 85 & 86 are your coil, you have these connected to your parking lights -ive and +tive.

If you want these to function as indicators during the day, and as parkers at night - this may work.

Pin 30 - +12V from battery
Pin 85 - trigger wires from flash and parker circuit* *diodes need to be used to stop each circuit backfeeding through one another*
Pin 86 - earthed
Pin 87 - connect to your new light/s
Pin 87a - blank

Basically, you will need to tap into your parker circuit and indicator circuit. Run a 1.5mm wire from both +ive wires in the parker and indicator circuit.

Run these into pin 85 (your trigger for the relay coil).

When your indicators turn on, it will trigger the relay and send a pulse to your new lights.

When you turn your parkers on, pin 85 will be charged constantly and not pulse, regardless if you put your indicators on or not.

Im happy to be corrected - I could be well wrong here as I often am :redface:

30 and 87a have a normally closed circuit. Therefore allowing current to flow through the relay when the indicators are turned on, allowing them to flash as per normal.

When the parkers are turned on, they turn on the lights as well as turn on the relay (thus + and - to 85 and 86).
Switching the relay on will open the 30/87a circuit, therefore not allowing current through if the indicators are turned on.

Make sense?

Yes I kind of understand, why you're doing it this way I dont understand.

Maybe its just too early in the week for me.

The way you have connected the relay would work if there was only ONE globe being used for both functions.

However, I will be connecting TWO globes in there - one yellow and one red.

Holding this thought

Holding this thought

If, as you stated, if a single wire (coming from point 87 on the relay) is connected to both lights (red and orange), then BOTH will flash with the indicators, and BOTH will stay lit when the parkers are on.

Therefore, I will not have separate function as required.

Am i making sense yet? :thumbsup:

I edited that post as I had another thought, which when looking back would not work. Hence the 'holding this thought' part of the post.

Cool - since you're using two globes and not the one globe I guess you can try your way. If they are ~ 20W globes factory wiring should cope aswell.

Only advice might be to actually earth Pin 86 instead of wiring it into the parker circuit.

The reason I did not quite understand your schematic, is I thought you were using 1 globe - had me scratching my head until your second last post.
