Upgraded LED tail lights/ now turn signal issue

[ezlnh8u]

 

Hello, I upgraded my square tail with some bluntech LED kits, everything works from brake lights to driving lights, except my turn signals, the turn signals worked properly with my old bulb set up. The led set up is pretty straight forward. Everything plugs in to the oem light pigtail.

 

Any suggestions on what might be the issue? I tested the led turn signal side for power and they are getting sufficient voltage to that section.

Could be inadequate load. LED's often dont draw enough current to make the turn signal relay actually click on and off.

 

Could rig something where you take the power wire run it through an old school bulb and then into the led turn signal. If everything starts working it proves that the turn signal relay needs more load. They make resistor boxes for LED's to add more load.

Try this digital flasher relay, that may be your issue

 

for me it was

I used this from NAPA, I have LED bulbs from SuperBright works perfect.

I have one of those flashers, I converted to them last year, it so strange, I move the flasher relay a certain way, pressed against the back magnet of my speaker and they start to work. As soon as I let it go, it stops.

Superbright led’s has the correct resistor to make it work correctly.

The kit Blunt sell is from Classic Auto LEDs and has circuit boards on each side with the correct circuitry for direct plug in.

Suggest the OP check the wiring connections.  Mine never had a problem.

I checked all the current voltage on both units, and they seem to be drawing the correct voltage. The flasher unit works perfectly when I put it agains my speaker magnet. I’m confused. Lol.

That flasher is like $13. bucks I would try a new one just for grins.  That or buy a magnet.?

I have the same problem and have not solved it yet, but there is an earlier thread on this subject with lots of great info, search here under " dash indicator problem "

I upgraded to an electronic flasher, a while back. I was running led bulbs on the rear, and everything worked fine, now with the new led bluntech kits, the rear signals only work when the flash unit touches a magnet, I tried a new flasher and the same results.

That is truly strange. Do the hazard flashers work correctly ?

Same reaction as the turn signals.

I had a similar situation with my '74.  Following suggestions by Paul Winterton, JP5Touring, and SpuriousSpeedo, I replaced the flasher relay with a Grote 44890 (Equivalent to NAPA EL-13L1 or to CEC EF-33RL).  It has a fourth (pigtail) contact compared to EL-13, which connects to ground.  This flasher relay does not seem to care what kind of bulbs are attached, it just works.  See my June 18 post under "Signal flasher upgrade easy to do & what a difference" at the link below.  P.S.  The BluntTech / Classic Auto LED arrays are GREAT!
