Badkarma Posted January 16, 2013 Report Share Posted January 16, 2013 So the other day while making a left turn my left signal starts to flash at irregular intervals for a few seconds and then starts to flash quickly. I did a little trouble shooting, checked the only fuse I could figure just inside the drivers side door, it was good. Then I noticed the front marker lights were not working. So I replaced them figuring it may have caused the issue since they seemed to be burnt out. The signals will work properly for a few seconds then continue with the same issue as before. One thing I also noticed was that the marker lights are not alternating with the turn signals like they should, they are flashing at the same time. Now I'm stumped. The only mods I have to my lighting in that regard is Hella LED tails and they seem to be working fine, though they do speed up with the signals when they act up. Far as I can tell it is only the left side. I dont get the same issue on the right side. Anyone have any thoughts? Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted January 16, 2013 Report Share Posted January 16, 2013 I would check the grounds and clean them off as a start. I would pull turn signal bulb and check for corrosion in the socket as well. Quote Link to comment Share on other sites More sharing options...
cleansss20 Posted January 16, 2013 Report Share Posted January 16, 2013 Mine is doing the same thing...I know sometime when lights go out it does it to let u know u have a light out. My daytime running lite comes out sometimes but it never does it on the right side. Just blinks fast when making a left turn Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted January 16, 2013 Report Share Posted January 16, 2013 I have never seen a bad bulb flash normal and then fast. normally like said the signals will flash fast when that filament is toast. You can try and replace that bulb and see what happens. Quote Link to comment Share on other sites More sharing options...
Badkarma Posted January 16, 2013 Author Report Share Posted January 16, 2013 I'll take a look at the bulb and socket when I get a chance today. Still has me wondering why the signal lights and marker lights are not alternating like they should be. Ugh, I hate electrical lol. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 16, 2013 Report Share Posted January 16, 2013 How long ago did you install the LED tail light? Might want to try reinstalling the original tail bulb and see if the problem clears up first. I have heard of these LED modules causing some really whacky problems with peoples vehicles....

Badkarma Posted January 17, 2013 Author Report Share Posted January 17, 2013 I was thinking that on my way into work tonight. I put them on close to a year ago. Didnt figure I would have issues since these are cheapy ebay brand. Ill swap in the stock units this weekend and see what happens. Quote Link to comment Share on other sites More sharing options...
soldadoblanco Posted January 17, 2013 Report Share Posted January 17, 2013 When you install led lights you need to also install a resistor I can't remember exactly what ohms. But I had this problem as well all my exterior lights are leds except for my high and low beams and I would experience hyper flashing until I added the resistor to the front turn signal Quote Link to comment Share on other sites More sharing options...
Badkarma Posted January 17, 2013 Author Report Share Posted January 17, 2013 Negative in this case. The Hella units have a built in module for load equalization. That is not to say the module may not be having issues. Its an easy enough swap to find out http://www.hella.com/produktion/HellaUSA/WebSite/Channels/Drivers/Products/Performance_Lighting/Chevrolet_Silverado/Chevrolet_Silverado.jsp Quote Link to comment Share on other sites More sharing options...
