I have a led 3 brake light. And a couple of the lights dont turn off they just dim any ideas why?

 

Anybody

 

Do you have LED brake lights as well ???????

 

Led's require such low voltage to run that they'll pull off the residual voltage in the line or a trickle feed for hours. Usually minuscule power traveling through the system somewhere, and they'll pull off of that. If its bugging you that much, throw a resistor on them. No need to worry about them draining your battery.

 

Yes i do have led brake lights

 

There is your problem. LED bulbs will draw a very small amount of current if there is not a regular bulb some where in the system.

The amount of current is very small so you should be Ok.



The fix is to either put a regular build in the brake light system some where. Or wire in a resister.

 

Also sounds like have a ground short, a power wire is shorting to the truck body, it's not a huge problem, but a real bitch to trace every wire, or you can pull and replace fuses one at a time, if that light goes out you found the short, if not it is a major component.
