Hey guys, so i just got my bumper painted and installed it yesterday. While doing so, i swapped my daytime running lights to LEDs to get rid of the disgusting yellow colour.

However, my DRLs stopped working now. The highbeams work, so i know the bulbs are fine. I have previously repaired the module by resoldering it last year. I just took it apart and redid them all again to make sure. Still no DRLs.

I havent torn off the bumper again yet because i dont want to do all that work for nothing because my DRLs were fine before i swapped the bulbs. Again, the highbeams work but the drls dont for some reason. Could it be the LEDs cant run at such a "low voltage" if thats the correct terminology?

The kit i used and have used many times on other cars are LED EAGLE off of amazon.




Any ideas or solutions? Wanna get this sorted so i can finally put my ionic lip on!!!!

Thanks!

 

LED’s not being able to run at low voltage is a possibilty.

I remember some G35’s ran the high beams at half voltage as DRL’s.

Measure the voltage in the wires with the DRL’s on. If the bulbs arent lighting up but you’re getting 6 volts, then u have ur answer.

 

Thanks for the reply! Does the bumper have to be removed to reach the harness? I saw someone mention it may be possible to get through the fender liner. Sucks the bumper has to be removed just for the bulbs.

Thanks

 

On my coupe I can get to it thru the fender liner. Not sure about the sedan but I cant imagine it being too much different.

 

The Eagles replaced your halogen high-beams? I think Scorpi0 is right, DRL for '06 ran the high beam halogens in series which made them 1/2 as bright as normal. LEDs probably won't work at 1/2 voltage so you may need to do some further modding. Should be some more ideas from others coming soon...

 

Thanks for the reply. Yup this seems like the answer to me as well.

I read that some people have to buy a module to get it working on other cars, not this particular brand but leds anyhow.

I have emailed the manufacturer as well to see if they have any possible solutions. If not, i may end up having to just switch back to the halogens or live with no drls.

 

Well the manufacturer replied and said it wouldnt be a voltage issue as they would flicker.

They said since the high beams are working, but the drls are not, it may be a polarity issue and to switch the bulb around.

Not sure how thats possible as the h4 bulb can only plug in one way. Well, ill see what i can do in the next few days.

 

Hmmm... I wouldn't think the DLR module would change the polarity but who knows because the halogens wouldn't have cared. Just to be clear, '06 had one xenon bulb for low beams and one Halogen H4 which is a two filament bulb, 1/2 of which was for high-beams and 1/2 for fog lamps, sound right? Have you checked to see if your new LEDs work as fogs? Be aware that there are a lot of fuses involved so be sure you haven't just popped one. Your FSM for lighting (including Canada) is here:

And here is the illustration of your headlamp, just as an fyi.

 

Thanks for the reply. Im not aware if they work as fogs per say, but ive used this brand many times in the past and have never had issues, even with drls.

Yes thats correct, the hids are for the lowbeams, whereas the "fogs" and highbeams are the h4 halogen bulb. I guess i will check the fuse first to make sure its not blown as thats easier than tearing into the bumper again.

Ill keep the thread updated with what i find.

Thanks!

 

I dont think 6v is enough to make them flicker.

 

So connecting two 12v incandescent bulbs together in series logically means that they will each get 6v and thus be half as bright. The problem is LEDs don't load the circuit the same way as incandescents - or halogens in this case. For instance without the right resistors, LED replacement turn signal bulbs can cause a fast blink. And some guys who have replaced their in-cabin lights with LEDs have found that they never turn completely off because they're on a circuit that is built to dim the "normal" resistive load of incandescent bulbs.

I don't think the DRL unit changes polarity to the lamps. I think the + side of both bulbs remains + even though the ground side of the LH lamp becomes the + side of the RH lamp when in series. As far as I can tell from the description in the FSM, the current runs in the same direction. So since your brights work correctly I suspect the issue may be that these LEDs built to operate on 12v just don't get enough juice when run in series.

DRLs are still mandatory in Canada, right? Hope you can figure out a solution.

 

So i really dont desire to go back to halogen drls. And i really want to do something to set my car apart and make it look sexy lol.

I like to look of halos on the g, and would like to see if i can install those. Im getting a spare set of headlights for a decent deal and will be taking the lenses off to paint. Great opportunity to install halos.

My question would be, what kit is a good, solid reliable one and how can i wire it in? I mean, can it just be installed to the normal headlight circuit since i already have drls, or would it need a legit 12v source from somewhere else?

Im not exactly good at wiring as ive never really done much before, but it would be a great learning experience!

If its too complex, i may just go back to halogens and call it a day.

 

You'll probably want to find another spot for your DRLs. Nothing other than your standard halogen is going to work correctly with the original circuit. There are many great headlight rebuild threads in here so maybe some members will chime in with ideas.

But as far as you DRLs go, if you rebuild your lamps with halos (for instance) maybe you can find a place to add some bright LEDs to work as DRLs. Then there should be a way to tap off the power from the DRL module so that they only run when they're supposed to...

For instance, check these guys out (I don't know anything about this company):

Thanks for the reply, looks like my options are either aftermarket halo headlights, or paint the oem insides and stick with halogens.

I think the 2nd option is my best bet, read too many threads about aftermarkets having crappy output.

Thanks!

 

Aftermarket headlights have OK output. Not as good as the OEM projectors, but definitely not crap! Most people that complain about aftermarket headlights dont know how to adjust the beam in my opinion.

U can add halo rings to your OEM headlights since youre already gonna have them open to paint it. Wiring is easy. Supply and 12v line to it and it will light up.
