LED Tail lights on 1978 Chevy C-10

[wideboots]

There is an article in the tech section about Electronic Flasher units repacing Thermal Electronics Flasher units that is dated 25 November 2001. I am new to this web site so I just saw it.

 

I have just installed LED tail lights on my truck. The signal lights will not flash due to so little draw of the lights. Need a new flasher unit for these lights.

 

In the article it states: "It's very easy to upgrade your flasher. After going to the local auto parts store and buying the proper part (usually $13 or so), turn the accessory key on, and turn on a turn signal. "

 

The problem here is what do you ask for? The parts guy wants to know what the flasher unit came in (make, model, year, etc.). My 1978 Chevy 1/2 ton truck never heard of an electronic flasher unit. What do I ask for?

 

Thanks for any help you might be able to provide with finding this flasher unit for my old truck.

That is weird as I recently installed LED1157 tail light bulbs in my 78 K10 without the need for an electronic flasher. I guess my old 1157 incandescent bulbs in the front must have enough resistance to make the flasher work.

 

Got to love the discount auto part idiots behind the counter. Just walk over the light bulb isle and start looking at the flashers until you find an electronic flasher. The two-blade flasher that works in GM vehicles has not changed in over 40 years so any of the electronic two blade flashers should work fine. They can also be found in the trailer accessories isle as they are common for the RV folks to install.

Thanks for the info. I went down to Car Quest, and the electronic flasher unit cost only $2.47 and it did fix the problem. Interestingly enough I was about to purchase one from a specialty LED company on the internet for $35.00. It does pay to shop around before you jump. Thanks again.
