I was bugged by the threads from the WRXers about their side marker light not being on all the time, so I figured out a way that SHOULD work. It's posted on the i-club already, but I thought I would throw it in here too.

Here's my little picture:


I'd appreciate any feedback. Oh, you'd have to duplicate that for both sides.

There's an easier way. (I'm assuming you are talking about the fender repeater lights, and are trying to make them come on with the park lights AND flash with the turn signals).

Hook the power of the bulb to the park lamp circuit, and the ground of the bulb to the Turn siganl circuit. When you ahve just park lams, they ground through the T/S bulbs, when you have just T/S, they ground through the Park bulbs. When have T/S AND Park, they go off... So they will flash out of psahse with the turn signals. GM and most of the domestic companies did this for years on their front side marker bulbs. Note, it will only work with low power bulbs.. ie a 194 bulb like in the fender light.

Actually, if it's all hooked up exactly as the diagram, you will get nothing if the parking lights are OFF.
Yeah you will. :) The turn signal alternates on/off through the +12v constant input on the relay. So when the turn signal is on, it will put +12 volts through the relay to the normally-closed pin. With the parking lights on, the relay will direct everything to the normally-open pin, which has nothing hooked up to it.

It seems to me that if you did that, you'd end up with some odd things.
With the parking lights off, the turn signal would now flash the parking light and the side marker.
It might work, assuming the flasher grounds out when not supplying +12v to the bulb rather than just being an open circut, but wouldn't the parking lamp also flash bright/dim, due to alternating power?

If you tried it with a higher power bulb like a 1156 or 1157, you would get wierd back feeds and dim bulbs. But since the 194 bulb only uses about .3 amps, and it will have at least four other bulbs to ground through at all times, it works fine. It may not be at 100% brightness, but you won't be able to tell the diff. And the mount of current flowing throught it will not be enough to cause the larger park and T/S bulbs to glow visably. And I'm not saying that your 4 relay idea won't work, but a couple of the wires in it are not hooked correctly. They are labled correctly, but running the the wrong spot (relay 4 has 12C running to the output of another relay, that not really a constant power, but switched) The bulb will get power from either relay 3 or 4 from the N/C contacts, which have the common contact running to relay 2. If the parking lights are off, no power comes out of relay 2 and no power goes to the bulb. The theory is sound, just a minor mistake in the diagram.

Try this

Try this... N/C = normally closed contact, C = common contact, N/O = normally open contact.

--- = ground

They aren't labeled incorrectly, and they're not going to the wrong spot either. I didn't want relay 4 to have power 24/7, or I would have connected it to the battery. That's why it only gets voltage when the parking lights are on, coming through relay 2. It's a constant power source in that it provides the electricity for the end device. The switched lines only provide electricity to energize the electromagnet inside the relay. Relay 3 has the power coming from relay 1, going into the constant input. That juice will flow straight through the n/c contact to the bulb, causing it to light up as the turn signal energizes relay 1. My drawing is completely sound.

The reason that I used 8 relays, or 7 if #2 is common between sides, is that I was trying to eliminate drain on other circuts. Other people have tried to do similar mods but ended up with front turn signals that didn't flash, and rear signals that flashed fast, indicating a problem.

So if the turn signal circut has enough juice to energize four relays, in addition to the bulbs, without giving people grief, then so be it. That's great. I'm not so keen on putting the turn signals into the n/c lead though. All of the relays I've seen mark one as a 12 volt input and another as the 12 volt output. I suppose it doesn't matter, as the electricity should flow both ways barring a filter of sorts inside the relay.

I took the liberty of redrawing it so it suits my anality and I'm going to post it over on the i-club, giving you due credit.

I just want my RS to be like my old '92 Legacy. The side markers came on with the parking lights on that, and they blinked too. Is there anything wrong with wanting to go oldschool on my oldschool?

The solution is simple.

Cut the ground wire to the fender bulb and hook it to the park lamp feed.

I tried it on my own car just a few minutes ago, and everyting works o.k. The fender light becomes a park light that flashes with the turn siganl.

It will work as follows

1. park lights only, the bulb is on

2. Turn siganl only, the bulb flashes just as it always has.

3. Turn signal while the parking lights are on, the bulb flashes out of phase with the other turn signals. (when the turn siganals at the front and rear of the car flash on, the fender light flashes off and vice-versa)

No wierd back feeds or dimly glowing bulbs at all.

I cannot see them while I am driving, or I just don't look for them, so I guess it is purely a cosmetic mod for others to enjoy.

Ok, next question:

Can we wire the wipers to wipe in sync with the blinkers? ;)

Or have the blue squirters blink? :p

My Jeep did that.

But it got old, because I drive with the lights on 24/7, so I had to turn them from AUTO to ON. :)
