Hey folks. I recently took bed off 01 s10 to replace tank and fuel pump. Since bed was rough shape i added a wooden flatbed as its just a farm chore truck. I ordered some led lights for tail lights. Prior to cutting wires off old bulbs i identified each wire so I was sure for rewiring. I noticed i had a sporadic blinking turn signal during this time and assumed it was a bad bulb. There was a bad bulb on front and back. Replaced front bulb and wired in new led tail lights. I still have a fast blinking turn signal. What do you think could be issue? Bad ground somewhere? Appreciate your help/guidance.

It's most likely the LED's themselves, although a faulty ground could be the culprit. The LED's draw substantially less amperage than the original incandescent bulbs, You will likely need to add resistors before the LED's to compensate. If the rapid blinking only occurred after installing the LED's I would suspect them as the cause.

Even though they were sporadic prior to adding the led?

That issue seemed a little unclear (..."during this time"...) in the original post. If the rapid blinking was occurring prior to the LED install, then a bad bulb, socket, ground, or funky wire could be at fault.

Apologies if description was unclear. Hopefully you kind of understand what im seeing now. I assumed ground or something. Would you know how many volts to check for at each light? 12?.

I would think so.

I believe your fast flash is due to the LED themselves. Reason being is load resistance. Most budget LED or bulbs do not have enough load to properly cycle the flasher relay. If you confirm that all 4 fast flash it is load. Couple ways to fix it. Add load resistors to the LED circuit or change you flasher relay to a full electronic relay. The electronic flash relay for retrofit LEDS have a small timer in them that cycles the power without knowing or caring the load. The problem prior to LED conversion could have been flasher or ground related.

There are tons of write-ups about LED load resistors that are easily found, my solution maany years ago was to replace the flasher relay for one built for LEDS. As i recall it was not expensive and a lot easier for me that cutting in load resistors.

I think this is where i bought the flasher, however no endorsement to the website or seller.

I appreciate your input. Id say you are probably correct. When i put on the Hazzard lights all 4 lights (front OEM, and rear led) flash properly. I think i will splice in those resistors and see where that gets me. Thank you

I like your method of dealing with the continuous, never ending question of should I hack a hole the floor of my bed or lift it up to fix my fuel pump. Just throw it away. Now that is a man who knows what he wants. Bravo!

The resistors should easily cure your little problem.

Far from knowing what's right to do.. haha appreciate it though. Truck only has 109k miles on it so i want to be able to get to things easier if need be. Anything i would have in bed can easily be hauled on flatbed. Pull a 5x10 trailer for 4 wheeler anyways. Hoping ill get issues fixed, annoying haha!

My local oreilys had a relay and that fixed my issues! It was located behind my glove compartment. Appreciate the help
