LED indicator light woes....'69 Camaro

[beeler311]

So I had LED tail lights with no issues. I installed LED front indicator lights and now I have problems. I also installed 2 new flashers as well. This is what's going on:

With headlights off:



Signal lever to the left - Hazards flash
Signal lever to the right - All normal
Hazards on: All normal


With headlights on: (the left dash indicator is always on)

Signal lever to the left - Nothing happens. There is a single click of the blinker. No lights though.
Signal lever to the right - All normal
Hazards on: Only right hazard flashes

How would I go about diagnosing where the issue is? I've got a voltmeter where I check around, just not sure what I need to be looking for. Thanks.

Are you you saying you put LED bulbs in your turn signal light housings? Sounds like the left front one is messing things up. First, check to see if your grounds for the housing/lights are good. If your grounds are good, try and turn the bulb around 180 degrees in that socket. LED bulbs have to be put in the socket correctly (the polarity to be right). If that doesn't work, try putting normal incandescent bulbs in those sockets to see if the problem goes away. I had a similar issue but had 2 bad LED bulbs in my front parking/turn signal housings, I ended up putting OEM incandescent ones back in (even though every other bulb in the car is LED). See if that works for you and let us know.

I have LED lights front and rear on my C10. In the beginning I had issues with the turn signals not working so I replaced the standard flashers with the expensive LED specific flashers. The turn signals and hazards still wouldn't work. I ended up putting the standard flashers back in and added a pair of load resisters in line. Now everything works like it should.

No, I bought Marquez Designs housings with the bulbs. I will try putting a regular bulb in that housing and see what happens.

That's good to know. I may try that if I can't figure out what's going on. Thanks.

What Velcamino said. There is a special flasher module needed for LEDs if you simply replace incandescent bulbs with LEDs. Go to https://www.superbrightleds.com/ They will have all you need to fix this issue. Also, I believe there are two flashers. One for sin gals and one for hazards. You will need to replace both.

I did replace both flasher modules. I think he is saying to try a load resistor instead of the flasher modules.

Thanks. Do you know which of those fits a 69?. They've got a couple 2 prong units. I don't have mine in front of me and they couldn't tell me.

Well I fixed it. Not sure exactly what the problem was. I replaced both bulbs, both bulb sockets, and ground the ground contact points down again. Thanks for the help guys.
