[REQ] BRZ Halo Lights always on w/ Ignition
 

Hey, has anyone made it so that the halo lights (or whatever you want to call them) are always on when the car's running?

I'd imagine it's a fairly easy mod but I'm afraid to go off and do it without any guidance -- LEDs can easily be burnt out if you don't give them the proper voltage / amperage, also there's the fact that some of you probably know of some convenient wires to tap in the area, so I thought I'd put a request out there and hope that somebody's done it before :P

You can look up my thread I did this mod, but with Halos for my FR-S. I would say u would have to isolate those wires cut them and plice them into the same wires I used. This is not very simple but can be done. I haven't seen the BRZ wiring though.

Can't you just throw a relay off the DRL's and have that switch the Halo's on? Snip the Halo positive lead, throw it on the relay, then find a switched or even constant and put it on the relay?

Can this be setup with Toyota Techstream ? *

Bump nobody?

This is something I definitely plan to do, along with the LED strip, just haven't gotten around to doing it yet. Ill post a basic DIY when I do though if no one else has done it yet.

Thanks! It would look sick

what led strip?

I guess it may not be considered an LED strip to everyone but the lights in the lower portion of the bumper, above the limited's fog lights. I dont like that they turn off when the headlights turn on.

Possibly, but I didn't see when I was poking around.


Did some quick looking at the circuit diagram. One would have to energize the tail relay to have halo lights on (along with side markers and tail lights).
The relay is inside the body ecu by the left driver's knee box. One has to ground pin 50 of 3A connector to energize the tail relay.

In the same connector on different pins there is a signal that energizes some ignition relays, so I'm guessing it should be good.
So throw another relay that's activated by pins 15&12 of 3A and connects pin 50 to Ground. To be completely safe maybe some diodes are needed into whatever connects to pin 50 (can't find what it is), not sure. It's been a while since I did any wiring.

Now someone should try it ;)

On a second thought (given that I didn't find where the pin 50 goes, unless it's unused completely), it's probably safer to wire the relay trigger to some ignition lead on the 3C connector and make the relay connect that wire to 3C pin 12 or 13 (forgot exactly which one feeds the halo lights).

Was so excited to see this post! Did anyone ever get this done??? Please respond!

Ill get around to it eventually, pretty low priority for me. Been busy at work lately, but eventually I will do it.

One thing I wanted to know is that "halo lights, or big "L" lights I call them "sexy lights" for the BRZ anyways, but is there a way to make them brighter or as bright as the day time running lights? Those lights are hard to really see during the day and its like what else are they useful for?

I was going to remove my DRLs, paint its housing black and install a halo ring around the projector and wire it to the DRL. Then said meh. Because of school being a factor.

You are looking for the black and green wires coming out of the back of your headlight the green is the positive for your led and the black is the negative.

I did try to get to that pin 50 in the diagram I posted. It's on the back side of 'body integrated unit'. Not too hard to get too, but it's kinda cramped in there to try to add wires to the harness.

The pin itself is unused, but I'd need a metal contact core (not sure of the proper term) that goes inside those plastic harness connectors and to which the wires are soldered to. Not sure where to get one that would fit OEM connector. Gonna look around.

if you contact @SVXdc he may have a source for the pins.

Thanks, didn't think of that.

Ok, so I finally added a terminal to the OEM connector, and so far it worked as expected: with engine off the halo lights come on when I ground pin 50 pictured above.
So, tomorrow I'm gonna tap some ignition fuse to trigger a relay that would ground that pin whenever ignition is on and make sure this works with engine running.

Please post results... subscribed!

Ok, it works, but has an unfortunate side effect.
So here's a recap:
1) I added a wire to pin 50 of connector 3A on the back of the 'body integrated unit'.
2) Grounded that wire through an ignition-switched relay (tapped into one of the fuses on the bottom of the 'body integrated unit' for a source of ignition).

Results:
Halo lights (and all other parking markers) come on with ignition, stay on no matter what position the headlight stalk is in. Headlights work.
However, triggering tail relay seems to be what's controlling the dimming feature of the navigation unit in "headlight" mode. So by having halos on navi unit is sent into night mode. Which is really unfortunate (although not unexpected now that I think about it), since navi going into night mode is a major annoyance cause the unit can't seem to read/calculate sunrise/sunset time off the GPS network.

If I pull the fuse in the "panel" line on the diagram above, the navi stays in day mode; so I think if I turn that fuse into a relay that switches on with actual headlights it's gonna be fine. Gonna see if there's a way to do it.

Ok, new plan, 10000000 times easier.
1) Pull the TAIL fuse,
2) Take ignition switched power off the fuse for pass. side bun warmer (not used by me anyway) and route to the exit of the TAIL fuse.

Should do what I want. Will report tonight.

UPD: works as good as one can hope for if one doesn't want to cut into factory wiring. The only drawback - you can't put fuse block cover back on. I might procure a spare cover and make holes in it later.

All you need is two of [ame="http://www.amazon.com/Littelfuse-FHA200BP-ATO-Add-A-Circuit-Kit/dp/B0002BGELQ/ref=pd_bxgy_auto_img_y"]these[/ame] (or even [ame="http://www.amazon.com/Bussmann-BP-HHH-ATM-Add-A-Fuse/dp/B000GKEXK2/ref=pd_sim_auto_1#productDetails"]these[/ame], can't figure out from the pic if this one has two fuse seats), and three fuses.

Connect wires of both tap-in adapters. Insert two fuses into the adapter that will go into the source of ignition-switched power (I used RH seat warmer). Insert one fuse into the adapter that goes in place of "TAIL". Pick one of the two slots so that there is no connection between the legs (as if original TAIL fuse blown) of the adapter. Don't remember exactly which way should the adapter go into the TAIL fuse, but if you get it wrong your halo lights will be off and your navi will be in night mode all the time. If that happens - rotate the adapter.

If your car blows up while doing this - don't blame me, lol.

UPD: quick picture added.

And not a single fck was given, lol.
Some more notes:
1) It is feasible to separate the tail lights, so that you only get Halos and side-markers come on. To do that - pull terminals 12 and 13 of the 3C connector on the front of the 'body integrated unit' (you're gonna need some very-very thin screwdriver or possibly a needle) and connect them to the wire coming off your source of the ignition (RH seat warmer in my case). You don't need a second adapter in this case and you can leave the TAIL fuse in place.
2) Separating Halos and sidemarkers - I don't know how to do it. They are both fed by the same power wire coming off the 'body integrated unit', which then separates into two and the wiring diagram doesn't label the location of this junction.

Thanks for looking into all this!

It would be safer to run the halos on clean 12V, so two things: relay and regulator.

I will get more into this later today.

Thank you guys!

This is something that really bugs me with this car... I would love to have the halos truly act like drls.

:iono:
What's there to look forward to? Read posts after the one you quoted.

Ok, I did this a bit different, I pulled a jumper wire from the power out pin of the DRL relay under the hood then routed that power to the input of the power wire to the headlight height adjustment and that powers up the Halo's, side markers and tails any time the DRL's are on, and this also powers the DRL's any time the other lights are on.

Next time I get a chance I will be routing that power to the + side of the Halo's only right at the connector to the headlight assy. then I will install a Diode to block the power from getting to the rest of the lights and the dim relay so the result should be halo's and DRL's on any time the car is on. This will have to wait until I have another weekend with nothing else to do.

Couldn't you just put a diode on the original halo power wire?

To achieve what?

Nevermind, I read that wrong. I thought you were splicing in power to the halos and it was backfeeding and triggering the night mode. Nothing to see here.

Surprised people arent all over this. Seems like one of the first things people would have done

I am confused of what's going on here. Are you making the halo's (boomerang) a separate entity? I just switch my headlights knob forward so I only have the halo and DRLs...whats so hard about that.

This switches Nav/stereo to NIGHT mode. Would be nice to have those lights always on

gotcha.

So this mod is done. Also the drl's are now on even when the headlights come on.

Just go into info, then settings then scroll down and put your dimming on time or Manuel on your head unit then you dont have dimming or night mode when you roll the knob once for them to be on in daytime

Any chance you could add pictures or video on how to do this? Sounds simple but I dont want to screw anything up.

Much thanks
