Default Making corner lights into blinkers?

Hello,
On a 2002 WRX sedan, could you make the orange corner lights into blinkers and have the original blinkers (modded to clear) made to work with your driving lights?

aren't the corner lights already like blinkers? you would just have ot rewire the turn signal bulb depending on when you want them on. you can use a relay to turn on the turn signals with the blue/red wire in the headlight harness (common power for low and high beam, 12V when ignition on and headlight on) at your 85 terminal, 86 to ground, 30 to power source - battery would be best, 87 to the turn signal light bulb. that should work

Blinkers = part of headlight assembly

Corner lights = part of fender

This mod is already up on scooby mods. Well atleast part of it. Instead of just covering up the old turn signal leads you could just run them to the normal turn signal. I doubt this is legal though.

I did it this mod by the directions listed and it looks great

How does the side marker connect to the ground when it's flashing with the turn signal and the light switch is off? Is it through the front marker (parking) bulb?

Yeah. Basicly you disconnect the existing wire and wrap it up. Then you splice wires to run the side marker off the same wires that run to the front marker (parking) bulb.

So with the light switch off and the turn signal flashing, the side marker is connected in series with the front marker. The two bulbs are the same (5W, type 168), so each sees 6 Volts. Both of them flash, dimly, in addition to the turn signal which works normally. Can anyone with this mod confirm?
It seems that to rewire the side markers correctly, one needs to ground the parking lights positive feed when off, instead of leaving open. That can be done at the illumination relay.

Basically you cut both wires to the sidemarkers. The power lead gets spliced to the power lead for the parking light in the headlight assembly. The ground lead gets spliced to the turn signal power lead. That way, with the parking lights off, the sidemarkers will also be off, but will blink with the turn signals. When the parking lights are on, the sidemarkers will be on also, and will blink alternately with the turn signals. There is no loss of voltage, all bulbs will be normal brightness. I even have an extra set of sidemarkers mounted farther back on the fender near the door, and there is still no noticeable drop in voltage or light output. Hope this helps. I think if you wanted the front parking lights to come on with the driving lights, it could be done, but I'm not sure why you couldn't just turn your headlight switch to the first click with the driving lights on, since this would have the same effect.

What I am asking is how the circuit is completed to the ground when the lighting switch is off and a turn signal is flashing. Can you verify that the current path is indeed through the front marker bulb, and that the two bulbs are identical? Does the front marker also blink? In the other case, when the blinkers flash with the light switch on, the ground path from the side marker is through the main turn signal bulb which at 27W has much lower resistance than the 5W marker, so most of the voltage drop is on the smaller bulb, and that's why the mod works. But what about the former case? I looked at the schematic and couldn't see how this would work on GC/GF/GM, if one wanted the side blinker to come on with the lights.

Default "mystery" solved

Found the answer: the ground path is not through a single front marker, but through all 4 of the front and rear marker bulbs, plus the instrument panel and license plate lights, all connected in parallel with each other and in series with the blinking side marker. That's the same as having at least a 5W x 6=30W bulb in series with the 5W, so everything is fine, as long as most of those bulbs aren't burnt out. In fact, only about 1/6 of the side marker current flows to the ground through the adjacent parking light, and the rest goes back to the junction box and then through the other bulbs. And when the lights are on, the side marker is grounded through both front and rear turn signals on one side.

Just completed this modification. Definitely a must-do if you have an 02 or 03.

The color combo on my wires were slightly different. To make it easy, black will be the ground wire on both the running light and the blinker light. Just tap into the colored wires and it'll work fine. (My manual on CD didn't match the colors on the posts).

You'll like it even better if you go with clear markers and yellow bulbs.

Default No need to cut both Sidemarker wires.

Sorry to bring this thread back from the dead, but I just did this mod after reviewing the wiring diagram in the service manual and found that there is no need to cut the sidemarker lead (RED/YELLOW) wires. If you look at the diagram, the sidemarker and parking light (clearance light) are already sharing the same lead.

So all you need to do is cut the ground wire (BLACK) on the sidemarkers and splice it into the turn signal leads (BLACK/GREEN on left & Lignt GREEN/BLACK on right). I spliced it right where the turn signal wires comes out from behind the headlight.

Its so easy and worth it. Get some of these in there too.
They wont get too hot here or in the headlight assemblies despite the statement on the package.


EDIT since you have clear corners and I have a smoked stock setup you may be blinding people with your super bright white LED blinkers.

they will get too hot in the headlight assemblies, i had one fail in the parking light area.

the sidemarkers will probably fine, but it will be far too directional of a light for use as a "marker"
