So my dad, sister and I all have c7 cars, there’s are both 2015 z51 cars and have the z06 style tail lights, they have the tinted led aftermarket side markers and dads has the tinted rear bumper led lights hooked up as brake lights as well. Now they bought the Morimoto headlights and installed them and after getting everything back together the right rear tail light doesn’t work on both cars. Now after taking one of the cars to a mechanic he found that there was too much power lose due to all of the led lights and this affected the tail lights. So after removing the led side markers and replacing them with the factory markers the lights are back to working properly. My question here is this, does anyone know what needs to be done or is there any tinted led side markers that would work with out using too much power? Would a resister help and if so where should it be installed? Any help with this would be much appreciated!

 

Resistor sounds like the fix. I don't have the engineering degree to give you the rating for the resistor but one of our smart guys might be able to help you out with location and size of the resistor.

A resistor is not the fix...the aftermarket LED lights draw too much current. They need to be replaced by another aftermarket brand that draws less current.
The BCM monitors the current draw and if it exceeds some threshold, it disables those 12V power feed to those lights.

 

I have the same thing going on with mine. @VetteLights has been working to resolve this with the manufacture.

 

I am sure someone knows the answer, I’m just looking for it as well, so we can get the cars back how we want them.

 

that is exactly right according to our mechanic, so what is the correction, do you know who makes the led side markers that draw the least amount of current?

 

This was what the warranty. Department from morimoto had to say about it. I will include the screen shot.

This is a screen shot of the reply I got from morimoto.

 

Well, that kinda sucks as an answer.

I have been working on this issue for about a week. First I thought I pinched a wire somewhere and have been chasing my tail. I also have the Morimoto headlights, tail lights and Oracle LED side markers. I am one not to give up and refuse to remove anything. Currently I am adding the rear LED lights to the aft section where just aft reflectors were located. I did have them as part of the brake light set up. Its been a while since I did electronic work but this is a pretty simple issue to overcome and utilize all of the lights.
Knowing that the lights work fine before turning on the ignition tells me that the added voltage used while the car is running is increasing the current in the LED sensing circuit to the BCM. This means the values are pretty close but out of tolerance and causing the BCM to shut down the right LED lights.
So the issue is to drop the current. a simple law (I = E/R or AMPS = Volts/ohms). several ways this can be performed, the easiest is to install variable resistors soldering them in on the positive lead to the LED side markers or adding LED in serial form to add resistance. I have a sneeky suspicion the OP above that added LED lights to his vents and so forth did them in parallel. Series wiring should decrease the current, the sensitivity of the BCM requirements is unknown. It is understood why GM lights everything in parallel in that it can monitor each lamp individually and tell when something burns out.
I am going to first wire my rear LED markers in series with the right LED side marker and see if that reduces the current to an acceptable value. Tomorrow I have some variable resistors coming and will add them in series at each side marker and adjust resistance in order to garner the correct resistance if I have no luck today. One drawback will be a reduced brightness but Christ they are blinding bright right now and could use a bit toning down. I caused an accident at work while I was parked in the parking lot and the nearby road had a guy gawking at my bright side markers a swerved into a car at the intersection and side glanced the guys car. LOL
I am sure I will get some flamers that say "It can't be done!" Well post away! I know it can be done, just takes a bit of patience and investigation. Too bad for 2K plus head/tail lights they don't sell a addon to counterbalance the added current. So far all I have seen is them selling front side markers, if that's a fix where are the rear side markers. SHISH! Don't get me wrong I love the lights but I have seen other LED addons add a unit to take care of current issues. I will repost with results. When it cannot be done is when I work best to make it happen.

 

 

MrGary, I applaud you. I'm the same way. I don't give up. If I want something, I'm going to make it happen. I have the Morimoto tail lights also and was having problems with them throwing error codes. So I pulled the back bumper again, per a user here telling us how to fix the problem. Wrapped the harnesses with saran wrap and black electrical tape.. Problem solved. Then I couldn't get the bezels to snap in. Working them on and off for says, I got them snapped in enough where they look good and won't move. I'm still working on that also. But they look too good to just abandon.

 

thanks for posting this, hopefully you can figure it out and help others to be able to run there. Are the way they want to, if you do please include as many pictures as you can. Thanks

 

MrGary2011,
have you been able to find any success in making all the lights work together? Im fighting the same issue.

 

I have not, I am running the led markers in my car, my dad is running the headlights in his car with factory markers, and my sister has unplugged her front markers and running the led in the rear, and the morimoto headlights. Nothing to report at this time.

 

I have the Mirimoto headlights and taillights in as well as the Oracle LED side markers. been thinking of unplugging the side markers to see what happens. I get about 45 seconds with all lights on when the car is running and then the passenger side park lights shut down. With the car not running I can turn on the park lights, and or all lights (including headlights) and they stay on for roughly 10 minutes before the car powers down and turns off the lights to save the battery. Found a corvette shop in Sacramento that has found the fix by re-wiring all the lights into a different circuit of the BCM. 10 hour job plus parts. Im just trying one last hope for a fix before taking the car to him for the rewiring fix.

 

I have the same problem with the Morimoto headlights, tail lights and aftermarket led’s side and tail reflector lights. Have you been able to solve this problem yet? I would appreciate any help.

 

No good answers at this point other than put something back to stock until you get the circuit back under the max load. Morimoto doesn’t seem to care, so I will not purchase anything from them.

 

I purchased the headlights and tail lights and after the headlights were installed, the passenger side headlight and tail light turn off sporadically.

 

if you already have the led side marker lights in take the rear one loose and see it that fixes the issue.

 

by the way morimoto knows about the issue but they don’t bother to publicly disclose the information, and I think that is sorry. I have an email from them where I contacted them and ask them about it, I will see if I can find it.
