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, 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:

I got an education on polarity when I converted my GMC 78 Royale's clearance lights on the roof. I bought all new led lights and hooked one of them up and turned the power on, and nada, nuttin', and scratched my head and exclaimed Wth!. So, out comes my trusty Fluke 77 and it told me the story. No rhyme or reason to the wiring. Polarity on all of them was different. So, turn on the power, check the polarity, hook up the led, repeat x 10. Same is true throughout the whole 12 volt system in the coach.
Incandescent's don't care about polarity. Led's definitely do. Now I check first, then proceed.
