Lincoln ls Led Resistors

[iivan]

my leds wont completely turn off , someone told me i need resistors and now that i have em i have no clue how to install em > Please help LvC !

I'm guessing you are talking about the interior lights. Just install like a 4k resistor in parallel with one of lights in the interior, I chose the rear lights because it was easier to work with.

i chose the under dash light because it is one of the easiest to get to the wiring at the bulb socket

my interior lights are stock sadly cant get the dome lights off.. im talking about the reverse lights license plat lights and side marker lights

I had the same issue with the side bumper marker lights. The LED's would still be on 4 hours later. I didn't want to add resistors or additional wiring changes etc. I took the LED's back, and ordered Chrome/Amber bulbs off eBay (I think they make Chrome/Red standard bulbs too). I have been happy ever since, never thought about them again. (Gave up on LED's completely).

the real issue is that the LS uses a negative trigger system, meaning that at the light bulb there is always positive 12v, and the computer switches the ground on and off, when the computer "falls asleep" there is a high resistance to ground, and a very small amount of power will flow through the bulb and the resistance. this same amount power still flow through standard incandescent bulbs, except for there is not enough power to heat up the filament enough to glow. since LED's are so much more efficient, that small amount of power will actually cause the bulb to light a little. placing a high enough resistance resistor in parallel with one of the bulbs gives the power another path to take instead of through the bulb so it wont light up anymore.

Its more of a hassle to return the bulbs then to just wire in a simple resistor

Since I had to go back and get a resister, I just returned the LED's to O'Reillys, and went back to standard bulbs.

I could have put in a resister, as I did all this from scratch (hand wired JTM45 Marshall Guitar amp kit).

I didn't feel like messing with the car anymore at that time. After reading 1LoudLS's explaination, it makes more sense and it's something that could be done should I reconsider in the future. At the time it was just a frustration that I didn't want to deal with any more.

Good luck to the OP, hope he pursues it further.

Wiring question for electrical experts

LDM that looks like some pro work there buddy. Please check out my thread on rewiring LS tail lights.

so how do instal resistors?

 

[jolinc01]

My plate and reverse LEDs turn off after about 30 minutes with no resistors.

so how do instal resistors?

Soldier one side of the resitor to the + side of the wire and the other side of the resistir to the - of the wire, done.
