For those with Parking Lights Disabled

[mr_robot]

How can I measure the voltage? The are no wires to the turn signals on the LCI headlights.

The circuit board is what activates them.

Correct.

With Parking Lights disabled/off, but with your low beams turned on, without turns enabled, is the circuit still ~hot / aka 12v~

J, looking at their description... could you not use a relay (or micro-relay) to take the PWM input of the signal bulb (BL/GN wire on headlight harness) and then output clean +12v to the LED driver's white wire (low power 50% brightness)?

Then take the positive wire from the sidemarker lights to trigger the yellow (signal) input for your halos.

The red (high 100% brightness) could be connected to any +12v acc and ground to any ground.

I included a diagram of the headlight but I didn't know (or more likely, remember) what year your X was. This is a LCI 2005 w/ xenon & ALC.

Wired as I describe above... I believe you will achieve 100% during daylight hours. 50% as soon as you activate parking lights (either by auto selection or manual). And amber signal as soon as the turn signal is activated.

I totally forgot about the sidemarkers - nor can I recall, but aren't the sidemarkers similar to our turns, aka, constant on when lows are on.

I tried a ad-hoc test with a relay with the turn as trigger. Default *parking lights on*-*constant 12V active*, it will still causing the switchback halos to freak out. I think the simple elimination of the hot 12V and just hot 12V when turns will alleviate the issue and now that you bring it up (spazzed moment), if I disable parking lights, I still have sidemarkers.

^My sidemarkers are turns only. They do not function as parking/running lights so are ideal for feeding clean 12v (I have LED markers there) to your halos.

Was the relay freaking out? Would the coil on the relay keep opening and closing?

[jsoto]

1st sentence is a win if if the sidemarkers are just turns. Still@work trying to get a deadline out. Like duh, I cannot believe it was not even on my radar . Thx for pointing it out. I think we're 50% back there with the switchbacks!

The test relay was a solid state.

In my case, it's LED - but we're talking aftermarket rings - with turn/switchback function coming off the turns/parking lights. It behaves fine (switchbacks) with lows off.
The issues is the constant 12V (PWM) that comes into play with lows on.

I think turning off turn signals may shut/SHUNT the PWM 12 volt , but the PWM is causing the funky issues on the switchback rings. Regardless, I feel at the end of the day, I would still want running amber sides when lows are on (some level of sidelight visibility) than no lights on the side.

Sorry to revive an old thread, but I am also dealing with this setup, and have run into some flickering of my angel eye issue. I've attached a pic of the switchbacks I received. With the yellow wire connected to the positive of my parking lights/turn signals, the angel eyes will light up white, at half dimness when the parking lights are on, and will flash bright amber when the turn signal is activated. I have attached the white wire to a relay setup that is attached to the interior lights, and also the positive of my fog light so that my angel eyes will activate whenever the interior lights come on or i have my fog lights on, and only then do the angel eyes shine at 100% brightness. Is this a bad setup? I've already noticed one of my halos flickers when its at full brightness, and i'm wondering if its the PWM from the parking light that is causing my problem, or if i just have a bad driver for the switchback, cause its only happening on one light.
