RS Headlight Flicker

I've got a set of RS headlights that was fine at first, 3 years ago. Maybe a year or so ago, they started to occasionally flicker. These days they seem to be doing it more often. I'm hoping I don't need all new light assemblies, those are so expensive. Is it possibly just a bulb replacement or ballast replacement? Is this a common issue?

Are they flickering at night or during the day while they are acting as your day time running lights ?

I notice it at night. I try to turn them off during the day, but I often forget. But I can't really notice if they are flickering or not during the day. The problem flickers are at night.

Where did you buy your harness to make the hid's work? Offer or someplace else. Usually they flicker during the day because the daytime running lights run at 5v and hid's require 12v to run properly. Check your voltage when you turn your headlights to the on position. They should be at 12v if not that is your problem.

Sounds like your ballasts are getting ready to go. Are you running the HID's as your DRL's? That's a no-no. There not designed to run at low power. Need to get relay's in there to cut them off during the day. The harness from Gen5diy is bulletproof.

If they are running at 12v and flickering is still happening then I do agree with SsMickey it's sound like your ballasts are going bad.

There both wright, and if you get new ballasts the lights will work like new for some time, but it will come back.

Relax guys, the whole point of the harnesses is that it gives full power to the lows, the HID's are not getting low voltage power during the day. I got the harnesses from Ottobody on this forum. I emailed them once and haven't heard back, I'll have to try again. Some thing the relays in the harnesses might be going bad, but clearly some also thing the ballasts might be going bad. How much do new ballast's cost and how easy is it to replace them?

I need more time to verify, but I THINK the lights might be flickering more in the day, not at night. If that's the case, that would suggest that the problem is more likely to be bad relays in the harnesses, and less likely to be bad ballasts, you think?

Relays tend to be pretty reliable. That being said, they do go bad on occasion and are relatively cheap to replace. I would throw some new relays in there and see what happens. If your lights still flicker, start hunting for some new ballasts.

The relays are inside the harnesses, not easily replaced as far as I can tell. But I suppose the easiest way to tell what the problem is, is to wait until the next time it happens, and simply turn the low beams on. That will up the voltage to full 12v, I'll see if that stops the flickering.

So I noticed them flickering today, in the daylight, with what should have been just my DRL's running. I turned the lowbeams on and the flickering stopped. I turned the low beams off and the flickering started again. At another red light (at red lights, I can clearly see my lights reflected in the car in front of me ), i tried turning on the high beams, and the same thing. No flicker with high beam, flicker started again as soon as I turned highs off.

To me, this strongly suggests that the problem is not in the ballast or the bulbs, but in the harness that is supposed to be feeding the lights full low beam voltage instead of DRL voltage.

Agree? Disagree?

I emailed Ottobody about it twice and they haven't responded. Now that I"m pretty confident the harness is the problem, I'll have to start emailing them more aggressively.

I agree, it sounds like you have a harness problem. Your RS lights should ALWAYS be getting 12v. The ballasts do not like DRL voltage and will flicker as you have found out. That is why GM has separate DRL's on the RS package.

My harness is supposed to be giving them 12v all the time, that's the point of the harness. I'll have to call otto and have them fix it. I hope they don't make me send my harness in for repair, that means i'll ahve to strip my bumper off and put it back together TWICE.

After a whole bunch of emails that never got a response, their whole website has just disappeared. This does not bode well for my headlights, that are now flickering more than ever when in "DRL" mode.

Quick fix for you.
Disable the DRL. there is a spring inside of the knob that makes the knob go to the auto position all the time, if you remove this spring you can have the knob in the off position during the day and move it to the "auto" at night.
This is one option and its free.

Or you can buy a new harness from a different vendor.

Good luck.

How do you get the knob off (hahahahahh)? I didn't want to do this hack but it seems like now I have no choice.

Instead of hacking your headlight switch, just get a new harness from gen5diy. His relays are accessible too.

Finally heard back from Otto. They told me I have to have the dealership disable the DRLs. Which obviously no dealership will do. And the whole point of this harness is to turn low voltage DRL into high voltage Low Beams, thats why the lights worked great for the first year or two. I guess I'll be buying another set of harnesses.

Sound like it might be a bad wire in the harness So some times you can pop the pins out with a small flat head like eyeglass flat head and pop the top so that they lock back into please or it could be a brake in one of the wire If you have a multimedia ck for Continuity both ends I might have missed it but do they flicker only after you have started moving or just when you are stop and after you have stop and played with them do they stay on

They flicker only when the DRLs are active. If I turn the knob to manually turn the low beams on, they are fine. Or if I flip the high beams on, it's ok. To me, it sounds like failing relays that are not triggering the increased voltage when the DRLs are on. It doesn't seem to me like a loose connection type issue.

Relays very rarely go bad a ran an install shop for 12 years and every body always wants to run to the relay I have seen two go bad 12 years and that was because they where be used in the wrong apparitions with that being said they are cheap and a good starting point but it sound like it might be the switch switch might not be thrown out Enough current to active aftermarket relay when Drl is active try the relays then try the switch

Use Multi meter ck voltage going out when using drl then turn them on using high or low beam turn car off to see what happens when turn back on watch voltage for drl
