Hi, My name is dennis. I recently purchased an 07 cobalt ss and stumbled across this site. I've been doing some mods mostly cosmetic and I really love the how to section. I've been into muscle cars all my life and never thought i would get into sport compacts.Boy was I wrong!!! Now for my problem. I just got a set of led tail lights from modern performance . I installed them and they seem to work fine but when I turn the turn signals on they flash very fast. I hope someone could help me with this. Thanks dennis.......

 

welcome Dennis and I too drove old american iron..can,t help on the signals

 

You need to buy LED resistors and put them in line...It will slow them down...Tech reason is that a LED uses less or 1/2 the resistance as a normal bulb..so the system thinks one of the bulbs are out. Just type in LED resistors on ebay and you will find what you need

 

You need a load resistor. Your car thinks the bulb is out since LED bulbs provide less resistance in the current.

 

Welcome to this site. This has been discussed before but I'm having trouble finding the post. You'll get some posts that you should learn to search -- but the truth is often threads get off-track and what you're searching for is in a thread titled something completely different.

Call Modern Performance for help too -- I think it is a resistor that you need to reduce the amperage to slow the flasher down.


This thread has a discussion on the fast blinking starting on page 7 but no resolve other than the discussion on a resister:

Actually, I recently found out that in line wont work, but rather you must splice from the turn signal wire (yellow) to the resistor to the ground (black). If you put them in line they will just dim the overall brightness of the bulb.

 

That's good information....can you post a Part Number of the resister, or the resistance needed?

 

Buy these: http://www.v-leds.com/Shop/Control/P...id/0/SFV/32481

 

That'll help the guys who need them....6 Ohm resisters.

Can you post a pic of what you did for the "unknowing"?

Thanks
