Led tail light issue

how the hell does that answer my question?????
the lamps are led (der) they are both the same bottom and top so how does that tell me which one i need????????
the light circuit and the brake circuit are different wires and can be wired to either top or bottom, therefore i still don't know which resistor i need.
the 6 or the 24?????? I only need it for the light circuit as the brake/run circuit works fine.
is the light circuit the 21w??? or is that the brake circuit????
We're not all as clued up as you on electrics you know.
Don't bother answering things if your gonna be a sarcastic idiot. as you can see i have followed this thread all the way and know exactly what it says.

My man...you're calling me an idiot...and you're the one that can't read?

fact #1 read post twenty...like "Exactly what it says"

Maybe someone else can spoon feed you the info if you don't want to read it...good luck


BTW, welcome to the forum

BTW, welcome to the forum

thats the one i QUOTED you moron. maybe you need to learn to read.
read my last post properly. as no20 states
"people put high watt resisters in the circuit to fake being bulbs 6 Ω for the 21w filament, 24 Ω for the 6w (top lamp)" "Exactly what it says" as you put it.
both led's top and bottom filaments are the same. no seperate 21w and no 6w top lamp.

now read mine n get your facts right. my run/brake circuit is fine.

i need to know which one for the light circuit (seperate wires to brake/run,) and that no20 as you say does not tell me which 1 to use as both led circuits are the same. it describes them as normal lights circuit. I NEED THE LIGHT CIRCUIT TO LIGHT UP JUST LIKE THE RUN CIRCUIT DOES ON THE BRAKE WIRES. not as clever as you thought you big headed idiot.

You have used a couple confusing terms that don't match standards.

You have been calling the "run/ning" light circuit the "light" circuit they are all light circuits.

The run circuit runs at full voltage and is incompatle with your lighting. Wire a 24 Ω resistor from that wire to ground.

You may still get an error because the brake lamps also don't pull enough power in which case you would need to wire a lower resistance resistor in parallel to the BRAKE circuit (which is actually run/brake circuit. ).

I would need to know what amount of current the circuit pulls when lighting both top and bottom to know the correct resistance to emulate the 21w filament but people usually use 6 Ω. It likely needs closer to 8-10 Ω but only trial and error will determine what level will prevent the error.

The problem is two fold:

1) you don't have run wire connected at all the car correctly identifies this as a blown filament.

2) the brake circuit has too low of resistance even when doubting up the lamps, so it will likely see this as a failing filament.

If you know the wattage of the LEDs or can measure the current going to get fixture when the brakes are applied I can do the math to tell you the proper resistor.

A 6 Ω resistor at 12v is 24w! That's similar to a small soldering iron so it needs to be a special metal resistor and should be touching metal to pull the heat out.

If you only need 10 Ω, the power drops from 24w to 12w or half so it's worth figuring out what is actually needed.

With any luck simply doubling up the lamps (which you did) will trick the car into thinking the lamp isn't blown.

ok well firstly thanks for the proper reply. sorry for the confusion.
i gather you mean the run circuit is the main back lights?
if they are incompatible then why are they in the connector? (never had a set of these before)
They are the ones, when connected, that are as bright as the brake lights so i guess thats where the full voltage comes in.
So why cant i put a resistor in that wire to lower the full voltage??

Also, the brake circuit (run/brake circuit) is absolutely fine and works perfectly without any resistors. Doubled up as you said. No warnings about brakes. The ONLY warning i get is because the main run circuit is not connected to anything.
Thats how ive got it wired at the moment and all lights/ brakes etc are working perfectly.
What i needed to know was about putting a resistor in the main run circuit so that i could connect the light fitting properly without any alarms going off.
hope i explained this right.

Run the resistor between the + and ground on that plug. Warning will go away as the resistor acts as the connection and is emulating a bulb. Easy as pie, a quick google will give diagrams too. I don't even think you have to plug the harness back in if you don't want.



Edit: You can see my resistor install here above the fuse box.

thanks. looks a good place to put it.
i will have to connect the run wire to the lights as the earth is all one on the original light connector. Or is there another way?

The resistor goes between the run wire which you don’t have connected and the earth / ground. you’ll probably have to add a piece of wire because you do want to attach the resistor to the metal bodywork.

Just keeping something else AW said in mind also, be sure to insulate that resistor, it will her hotter than heck when the lights are in use . - easy fire hazard for sure.

I measured one once. Think it was about 250 degrees. Definitely mount it to a metal surface and keep away from things that don't like heat.
