I recently installed a set of front LED parking/turn signal lights... I am having a wee bit of an issue, as follows...
during the day the turn signals work perfectly fine. turn on the parking lights, and that's all I have. no more turn signals. I do have the electronic flasher installed, and they work fine during the day. turn the lights on, shows over.

Trying to figure out whats wrong with it. Do I need to hard wire instead of using the socket?
Shawn,

Be patient, I am sure we can figure this out.

Did you install a single replacement for 1157 LED in an OE front marker / signal light housing?
You say it works with the marker lights off, but please give a better description of what happens when you turn on the marker lights.
Do the lights come on and stay on (on, but no flash)?
Or, do you just get nothing?


There is a very high (outrageously high) probability that there is a bad ground in the marker light assembly. I have had to build in a new ground on all of mine.

Matt
Matt, No, I installed the whole complete one with about 30 led's in it on a circuit board...
Shawn,
That is a nice looking part, but you still did not completely describe the issue:
Do the lights come on and stay on (on, but no flash)?
Or, do you just get nothing?
Matt




If I remember correctly there is an issue with using LEDs in the turn signal/front marker light circuit.
The side marker light gets it's ground from the filament of the front turn bulb and the LED will not allow the reverse path like a incandescent blub will.
Look thru the archives I think there is a solution there.
