Front Turn Signals are dim with Headlight switch on

[DMC5180]

Thanks for this suggestion, I'll flip those connections, as I didn't do the High Beam lights when I installed the whole set. Hopefully this will solve my "dim bulb" problem in the high beam lights too.

In my further testing yesterday, I found the 1157 LEDs don't work very well at flashing. I replaced them with the 1157 incandescent bulb, and flashing is normal.

Not sure what you mean by don’t flash very well. Fix the headlight issue first then test the signals again.

My LED signals flash at a normal rate. It’s just that they go ON/OFF instantly.
They ramp up/down like a a traditional filament bulb.

Are your Halo housings full LED or H4’s

What do you have in the Inner High beam locations?

Changing/reversing the connector didn't solve the "stray voltage" issue as seen in photo.

All the bulbs are H4

LEDs when installed (without headlight switch on) work as they should. When the headlight switch is on then the LEDs are dim and don't flash correctly as you describe.

Okay guys, I pulled the #15 fuse (power to high beams via relay) and the problem persists. So now the 'stray voltage' is somewhere in the low beam circuit, maybe the turn-signal lever, aka. Dip Switch is faulty and 'leaking voltage' to the low beam circuit ?

Do you have any alarm system? Keep pulling all the fuses until you see the light go away.

[ritztoys]

No alarm system, total electrical is stock, no alterations. If I pull #14 fuse it will go away ( dim high beam filament glowing ), but also no low beam headlights either.

In my recent post ( #13 ), it is kinda confusing. I meant to say the leaking voltage is going through the low beam circuit to the high beam circuit , causing the 'glowing of the filament' in the high beam bulb.

Sorry, my memory failed me. I told you to swap the outer positions. It should be like this illustration for the outer housings. The ground and LOW positions get swapped. Also configure the Inner housing connector with the Ground and HIGH feed to match.

Thank-you Dennis,

This is what I was thinking, that maybe I moved the wrong wires and the incorrect positions have contributed to the 'stray voltage' powering the High Beam filament.

So I'm hoping this solves my issue, as I only did simple changes/additions to my cars electrical system. After my morning coffee, I'll take out the outer headlights and check ( PITA )

The high beam sockets/connector only have two wires, so swapping them won't do anything. I think you have my answer in the above diagram.

Dennis you where spot on with the wiring diagram you offered, I had the 'High Beam' and the 'Ground' connections reversed!

If you ever get the chance and find yourself in Indianapolis, stop by I owe you a few beers at least, Hooray for simple fixes!
