I just got a white lightning LED line of fire from Wayne the other day, (it's the one that turns white in reverse) and I figured it'd be easier to plug it right into a flat 4 pin wire harness for a trailer. Don't haul anything with my truck so I bought the wiring harness and plugged the line of fire into it, now..

The parking lights are not dimming, i.e. when the parking lights are on and the turn signal at the same time you can barely see a difference if anything

when the brakes are on and the turn signal is on, it blinks and shuts off the respective side completely and out of sync with the turn signals on the truck

So.... we hooked it up to a trailer to see if anything acted up, brakes, running lights work fine, but the turn signals are blinking fast as hell

So what the hell am I doing wrong?

 

LED resistor? mine doesnt do that but all my lights are LED

 

Zach had a similar problem. I am sure he will chime in.

 

yepper i think its a problem with our 93-99 3 bulb rear tail lights we have to get that modual to convert the tailights to 2 bulb for the trailer... well when the park lights are on it doesnt blink very well first one i had a 4 plug extention and cut the park wire so it only came on like normal when the lights where on and didnt stay light up...

wayne gave me a new one it helped alot BUT it still isnt even half as good as the 00-07 trucks that i have seen with them..

i think its just a flaw with the 93-99 trucks

 

Well I called the trailer place and there just happens to be a guy there with a 93 ranger with the same thing, he said I need a power converter, pretty much just has a lead wire that goes to the positive terminal on the battery and according to him that will solve all the problems and I will be peachy.... so we shall see
