Truck LED Help
I have a 2006 Ford F-150 and I'm pulling a jet ski trailer. It has two yellow running lights at the front then two break lights at the back, well I was at wal-mart in their boating part and seen they offer LED Running lights. So I bought 4. They are 2 yellow and 2 red. All 4 have 2 LEDs each. I wired them into each break light. Into the running light wire. But when I turn on my lights on the truck if the LED lights come on the running lights on the break lights wont come on. So I first thought I messed up and didn't get the power to the break lights on good enough, but it was fine, So I checked the ground wire. And if I took the ground wire off for the LEDs the break lights will come on. But if I put the ground back on they go off and the LEDs now come on...
I have the truck is putting out 12v to the running lights. But shouldn't everything still come on?
It says they Operate from 8-16 volts.

I have Order Number V168A and V168R
Maybe someone here can help?

LED's don't work like regular incandescents. Did the package say you could hook them into a circuit that has regular brake lights...that might not work. Just a thought. Maybe someone will chime in with some experience with that particular type.

Only thing it says about wiring is "Hard-wired with separate lead and ground wires for mounting to all surfaces."
If they wont work with regular brake lights how would I go about getting them to work?

And what if I replaced all the lights with LED lights.. Would it work then?

Led lights will not work on the new fords. You need to put a resistor with each led. I had led light bulbs in my taillights. Didn't work that great, so i took them out. The resistors were 50 ohm by 12 volt i believe. I will put the right info for the resistors when i get back home tommorow.

Only S/T/T
Just a note...
LED marker lights will work without resistors... it's the stop/tail/turn lights which require resistors if you use the Ford installed flasher however, you can change the flasher and not use resistors
stx2006 I believe something is crossed in the wiring... If you replaced the existing marker lights with LED units everything including the existing brake lights should function normally. Wire one lead into the marker light circuit and ground the other...
If the trailer was wired correctly with a four wire connector here's the industry standard wiring colors for the circuits...
Brown - RH stop/turn
Yellow - LH stop/turn
Green - Tail/Running
White - Ground
Hope this helps...

Well I went and looked today before work and I did put it on the green wire. Now I do have two green wires coming into the plug, one is green with a brown line and the other is solid green... I'm gussing that doesn't matter.
I know the LEDs aren't pulling to much power are they? They pull less than a bubls did.

Well it turns out I got it working tonight! :-)
They look great I'm going to be changing all the lights to LED now.
But my problem was. They bulb in the trailers tail light is really two in one. And! On top of that I may re-do the wiring on the trailer cause I found some nicks in the wires and I blew a fuse in the truck. Now I have the left side working I'll put everything back together and tomorrow try the right side. Maybe it'll go better! HA!
:-)
And to the guy who said LEDs wont work on the new fords.. Mine are working! :-)

I meant to say, in the taillights, i had a set of 3057 light bulbs. They made the signal indicator go slow. When the resistors were put in, then no problem. I do have leds on the front of my truck that were fine.
