I know I mentioned this in another thread but figgered I'd dedicate a new thread to it.

Just as the title says, got an Anzo 3rd brake light assembly that's full LED and the problem is, the LED's for the cargo lights stay on at a much dimmer setting even when the switch is off.

After a quick Google search I found out I'm not alone. Talked to someone at Anzo and they said that it's a thing with Rams that, there's still a minute flow of current on the circuit that isn't picked up enough to illuminate the regular incandescent bulbs but is however enough to light up the LED's to a faint glow and that pretty much the only fix is to add a small resistor or resistors to each side of the cargo light circuits but he didn't know what size/resistance resistor to use.

Has anybody had to deal with this? Apparently it's not just limited to Anzo products. From what I saw in my research today, there was a few different brands of LED 3rd brake lights doing the same thing. There was even one guy who had the same problem with his factory light after he disassembled it and installed LED panels in it.

Please help.

Oh...lol. Forgot you mentioned that...[emoji41]

So would I need two, for each side? What size resistor or does it matter?

just one is needed, take the resistor and wire one side to the cargo light + and the other side of the resistor to the cargo light - and it will be fixed

So just any ole resistor?

when i had a 3rd that i needed to do that to years ago, i used to make electronics, i had what i linked you to laying around, i added that and it worked, im not sure what all resistors will work but it doesnt take much, if you have some laying around try em out

I just ordered a resistor from the above link. Now we wait. Its a 100ohm resistor and you install it between the positive and negative line of the cargo lights. It was $9.50 including shipping.

It worked like a champ. Easy to install. Just tap in to your power and ground for the cargo light and wah-lah

What Watt resistor did you buy? Could you send me the link to it? Would be greatly appreciated

Its a 100 ohm resistor. Got it from this company.

LED Flashers, Electronic Flashers, Led Protectors & Load Equalizers | Autolumination

They have a link that specifies for dodge led lights

I know this is an old thread, but need details on installing resistor. One post said tap into power and ground? Another said only one resistor is needed?

Just one resistor is all you need, hook it inline of the two wires like this....

I have a 2003 Dodge Ram 1500 and I had the same problem I used a 50 watt 6 Ohm resistor hook it up to the ground wire which is black and the cargo light which is white and it fix my problem hope this helps you

What I would do, is go to this website and shoot this guy an email. He will tell you which one you need. That’s what I did when I had my last truck. I put a full-LED third brake light on my new truck but it came with a resistor already soldered in.
