Oracle flush Mount light issues, need some input

[RhinoJT]

I have a 21 ecodiesel with the Oracle flush Mount tail lights. I have had them on the jeep for almost two years. Recently the passenger light stopped working, in a way. The blinker and brake light function do not work, however, when you turn the lights on, the turn and brake light function do work. The driver side is unaffected and functions properly. I have tried Recycling the settings on the taser and checked all of the connections and there isn’t any visible damage to wiring and everything is plugged in correctly. I am assuming this has to be an internal issue with the light, at a loss at this point. I contacted Oracle and of course I am out of the year warranty. They are seeing if it’s possible to sell me just the passenger light, but would like to see if anyone has any thoughts on how to fix it.

I had this happen. I would first confirm the light is the problem by swapping it to the driver's side. See if it has the same behavior there. If the problem travels with the light, chances are there's an issue with the board inside the light. If on the off chance it has no problems after swapping sides, you might have a truck-side issue. Easy test to make sure you're barking up the right tree.

I was ready to crack my light open to fix the issue, but Oracle stepped up and did a one-time replacement. At the time they also told me it would be possible to buy individual lights in the future. So I never went any further. If you're interested in trying to fix it yourself, I could try to crack open the broken one I have and see if I can help you out.

That was the next step, may have gotten a bit ahead of myself. I’m going to try that this morning and see what happens.

Now, I’m even more confused. So I swapped the lights, driver to passenger, and passenger to driver. Everything works just fine as it should. Both turn signals and brake lights work. When I swap them back, same problem. Passenger only works with lights on. So maybe jeep side issue.

I will take a stab at your issue; low voltage to the driver side. And if that were possible, the electronics of the LED tail light might be a bit too intolerant of a bit lower voltage.

Why do I imagine this possibility? While I have not looked at a schematic to see how the JT's rear light wiring harness is setup, I imagine that the harness\travels from front to rear, to one tail light, and then additional length of wire continues on to the other tail light. Just enough of a, slightly higher resistance to make a difference in the supplied signals to the LED's that might also be a bit too fussy on the supplied voltage-range. This is just a wild guess. Although...

I changed out the incandescent rear tail lights on my 2008 JEEP JK Wrangler with QUADRATEC LED tail lights. Excellent improvement. What is interesting is if you have someone turn on the lights while your standing behind the JEEP, the passenger side comes on first, and then the driver side. Every time. LED's are faster than incandescent but to me, this indicates it could just be the wiring harness travels to the passenger side first (in the case of the JK) and then reaches over to the driver side tail light. Like I said, just a guess. The JT might have the harness travel to the driver side first and then continue on to the passenger side light? Voltage a hair low, thus current flow is restricted just enough to do this? Not sure how that ties into the case when you turn on the lights, then the brake/blinker work except the path to ground may be improved from some value that is not truly zero/ground in one case but the path improves to nail down the ground path to be actually zero, not a "differential" value above zero. Somebody else might support, or negate this line of thinking. Do the Oracle LED lights have external resistors? If so, you might try swapping just the external resistors instead of the lights-with external resistors, to see if that helps.

Finally, I see your JT is listed as a 2022. That means your getting close to needing an Auxiliary battery toss out and change. Wonder if the Aux or the Main battery are struggling a bit. Does your issue occur with engine off, but not when it (and the alternator) is running? Which might overcome the burden of one or both battery(s) being a bit off their game.

Full disclosure: I haven't purchased a JT yet by the way. Still operating my outstanding JK which has given me zero powertrain problems. So far just one door lock and one occasionally sticky EGR valve replacements. Half a dozen halogen headlight bulbs in our high wind area until I locked down the hood bounce. And then upgraded to quality LED headlamp assemblies too. My JT purchase is, or at least was to be in 2024. The Auxiliary battery design has me leaning toward another brand. Not FORD. But every time I drive a Gladiator, it moves me back to it as my pick. I know the solutions to get around the AUX battery fiasco. Right now I think keep it stock during warranty and tear it out/upgrade it post-warranty. Meanwhile, I shall be interested in what solves your issue. If a replacement from Oracle which does not have a bunch of use-hours seems to solve the issue, it might crop up again after some hours of use. Then this could be a combination of slightly impeded electrical flow to this side of the JT AND the electronics in the light being a bit marginal in its tolerance for less than nominal voltage/current supplied to it via "hot" wire, ground not being truly ground (zero), multiple connectors building up resistor-like flow inhibiting.

Hoping its something simple to correct!! At least let us know if the issue changes when the vehicle is turned off versus when the engine/alternator is running. Have someone elevate the engine RPM 500 to 1,000 higher than idle speed to see if the alternator perks up its output a bit more than idle engine speed. Or do it yourself if you can place a mirror behind your JEEP to watch results while your JT is in Park, and your changing RPM via the accelerator pedal yourself. If your tail light works, then your problem might be just as simple as replacing one or both batteries. For another 2 to 3 years of service, and unfortunate expense.

If your 2022 JT was built in 2021, pretty good likelyhood that the motorcycle like, 12 lb (not much gut-content for constant use) AUX battery is, or will shortly need replacing anyway. The main battery might (might) last you 5-ish years even though its only warranteed for 3 yrs. Seems many owners are changing both batteries at the same time. Your call on what to do with one or both. These can be load tested with quality load testers and if you do that, make sure your testing each battery disconnected. But... since your JT is a 2022, you could have the batteries tested by the dealer and probably get a battery replacement covered under warranty. If one battery still tests good, which will more likely be the 47-ish pound Main battery, they logically won't replace that one for free.

I actually didn't expect this result.

Do you have the ability to bench test these with an independent 12v power source? That was my next step and I was able to identify the conditions that allowed the light to work normally as well as the conditions that caused it to be faulty. In your case, this would tell you what to look for on the truck.

Otherwise @storyg is on a good path too. Compare output voltages of the truck's left and right sides. When I do tests like this, I like to use two multimeters with alligator clips so I can have one on each side simultaneously as I create the test conditions on the truck. For this a second person in the cab would be useful so you can monitor the meters the whole time. Not sure how feasible that is for you.

Last thing I could think of is the passenger light connector became loose on a few pins when mated with the truck connector, but on the driver side it's a tighter fit and doesn't have that issue. Not sure how you'd test for that, I'd need to think on it more.

Sharpsicle and StoryG,

Thank you for the inputs. I haven’t had time to go out and check with the multimeter, makes sense something could be dropping voltage across the wiring harness. Another thing I did notice is the jeep is throwing a code for a bulb out, but for the front passenger signal, which works. What weird is the light has worked for over a year, and now it’s having issues. Maybe the external LED resistor is going bad, however the right tail light works when you swap it without issue. The only thing I can think is the right light might be more sensitive to changes in the voltage from with factory tolerances or just going bad over time. Curious to see if turning the lights on provides more to the back this causing it to work. If that makes sense, typing my thoughts as I go.

Thank you for the reply. I have allready submitted a claim and have some emails back and forth. I sent a few minute video on what is going on.

So in reading all this I now have the same problem. I have the passenger side light going to a halt when being used. It will blink correctly once then stall to a mere little blink (pulse) this is while the truck is running. But when you turn the truck off it functions properly as it should, then turn the truck on it’s fine. So swapped the lights as you did and it’s just that one light that does it on that side not when it is switched to the other side. Is it safe to say that it is the light fixture itself? What did you have to do in your scenario for a repair?

This is a known manufacturing defect from @ORACLElights on their first few batches of these. Contact their support and more likely than not they will replace, they replaced mine.
