victory! finally no more rear light our warning! got a pair of resistors for five bucks, the leds were a buck, two day shipping from amazon.
installation is so easy, the resistor plugs into the socket and led and that's it

i used big fat turn signal leds, then just switched the casing with a t10 bulb, way brighter than regular small t10s

What resistance are those?

Do you have ESS? Do you get any errors, at all?

At Startup? At ESS turning the engine off, at ESS turning it back on?

And, do you have a link to what all you used?

2015 sport no ess

Amazon Amazon

here are the resistors, they didn't work when i used cheap leds
Amazon Amazon

so i just pulled off the casing off those cheap leds and switched em with bigger leds from
Amazon Amazon

anyways thanks for the tip about the plug-and-play resistors, they totally work

Yes in these calculations we have to remeber that an incandescent globes resistance increases as it heats up. Ie, the higher the voltage, the brighter the light, the higher the resistance. The lower the voltage, the dimmer and cooler the light and the higher the resistance. Trying to calculate this is nigh impossible given all the variables of the lamp construction so testing current draw at around vehicle starting voltages is about the only way. This means we will actually end up drawing more current at running voltage as our replacement resistor will have to be lower causing a higher current drain.

The only other way would be to use a non linear resistor in the cavity behind the mount - ie use the globe as the load resistor in the cavity behind the light mount...

i also did another mod; my leds were too bright, they lit up the whole back area, the whole bumper and the ground around it, so using duct tape i taped up most of the clear plastic cover only leaving a gap so the light would shine directly down only over the plate, i think it looks really cool, the rest of the sides around the plate and bumper are completely in the dark

I installed those exact same resistors on my license plate bulbs this week, super easy, no more build out errors on startup. Question for you though, did you do anything special with the fitment? The OEM bulb plug fits into the housing tightly with a twist and that nice rubber O ring. The cheap rubber sleeve on the resistor lead that the bulb fits into doesn't fit tightly into the housing at all Though. I just poked mine in there and put the housing back in the tailgate and it seems fine for now... Wondering if you attached yours any differently though? (I was thinking about at least slapping some electrical tape over it to hold the bulb in the housing a little better).

glad it worked for ya, what led bulbs did you use?
i did the same as you, it just hangs in the housing, tape would be a good idea to hold it security

I don't even remember which bulb I got. I just ordered a kit off of ebay. They look pretty similar to yours, but they have one less row of the LED's on them. the two for the license plate were supposed to be "can bus no error" bulbs, but they look like all the rest and never worked.

If I come up with a better idea than the electrical tape, I'll let you know
