After offroading today a couple miles down the road I turned on my turn signal and it started blinking really fast. So I get home checked the bulbs and my rear LED lights and both look fine and both work. I checked the fuse looks a little rusty but im not sure if thats the problem or not. Still going to replace it though. Whenever I turn on my 4 way flashers all the lights work perfectly. Has anyone had this problem before? Is the circuit going bad? bar ground?

 

I don't know about LED light wiring, but on my truck the left turn signal started to blink real fast last week while I was out trailer camping. That's usually a symptom of a burned out lamp. The tail lamps on my truck don't use the more common 1157 push and twist bayonet type bulb, it has 3157 lamps. They pull out and push in straight. The filaments looked good so I pushed it in and out a few times to see if the connector was corroded. I found that when it was pushed all the way in it doesn't work, but if you pull it back out just a little it works fine. So at least in my case I have a connector problem, and will either have to clean it, or replace it.

I think thats a sign that the fuse is going bad. Simple fix.

 

+1 to this. I would start with the fuse then go from there.

Mine did that. It was a bad connection where the lamp plugged in. Or it's burned out.

 

Borrow a fuse from a dif location of the same amp. to test-its always a great idea to carry a back up assortment I pack hardcore when going off roading (usually fishing spots where there are no roads) extra battery-electrical kit-the works-

 

resister in the led lights is bad
