LED turn signal problem

I recently purchased all the bulbs for my pickup to replace my old Halogens with brighter LEDs, specifically the Philips Unltinon LED bulbs, my flasher clicks on and flashes just once then completely stops wether the hazzards are on or the turn signals. Is there something I'm missing? I alsoralso tried replacing flasher with an EP35 from Napa but instead it doesn't work or actuate at all.

 

Polarity of the bulbs if they are installed wrong the current can not complete the circuit .

If things worked before?

 

They blink once but won't continue to flash, the stock flasher clicks on a single flash then clicks off and doesn't continue to flash. Would polarity cause this? I'll certainly check them.

Side note, I tried placing a halogen bulb in the front socket and an LED in the rear on just the driver side and it worked, blinking fast, afterwards I tried with both the front and back replaced with LEDs and it doesn't work as stated before.

Thanks for your help and welcoming me to the community!

 

I bought the EP35L flasher from Napa, is there a different one I should have purchased?

 

If they're lighting up, then they're plugged in with the correct polarity.

Sounds like that flasher might be defective. You might try swapping back in a regular bulb and seeing if anything changes.

 

I just can`t get into these LED bulbs

I use the LED lights all the time no problems .

It would be my luck to get a bad flasher too

 

With the Halogen the circuit drew enough power to cycle the flasher, not so with the LEDs. Napa says it is an LED flasher.

 

Did you get a bad batch of bulbs?

Have a Meter to test the bulbs??

We know the flasher works!!

 

Thats interesting. Its almost like they're not pulling enough current to run the flasher - which is the point of getting an LED compatible flasher. I'd probably return the napa unit and get another one (I don't really have a recommendation on which, all mine are stlil incandescent).

 

I believe it's the Flasher and I'm going to try swapping it with another, I recently purchased one on Amazon and it is supposed to allow 0.2-20Amps. I didn't find any information for the Napa module but I believe this may fix my problem. I read about the in line resistors and I think it's just that the LED lights aren't pulling enough power to switch the flasher. I think by replacing it with any other module claiming 0.2-20A it will flash from the low power draw that these LEDs pull. If I were to add a resister instead, it would just increase the load on the system mimicking the Halogen, that's not ideal. I'll let you all know what the outcome is come Wednesday so thank you for your help and I hope it works!

 

No but adding more of a load will tell you that it is the flasher.

Swap in one of your other bulbs see if that is enough load to flash the 3 LED bulb if not try two.

I use the same flasher with 4 LED lights with no problems.

Good luck I am curious how this plays out.

 

I have this flasher from Napa. I’m running Feinex T5 LED strobes as front turn signals and they work fine, but I have incandescent tail lights still.

 

I would like to know the impedance of the flasher module and the LEDs current, I'll try to see if I can give their technicians a call in the morning.

 

Earlier today I was able to do so, I replaced the front driver with a halogen bulb and both my OEM flasher and the Napa worked, I suspect the flasher isn't as sensitive as necessary for the LED bulbs like you're saying. I will know soon! Hopefully I can call tomorrow

 

I believe the Flasher works with yours, as the draw from your rear Halogens is enough to trip the flasher, I may end up going this route too by keeping Halogens in my turn signals until I become a bit more educated to figure this out.

 

Ok!! The flasher I purchased worked perfectly! Thank you all for collaborating and helping guide me to the answer I was searching for.

To set the record, I purchased the iJDMTOY Flasher from Amazon, although I'm sure any CF14 .02-20Amp flasher will work.

I believe the EP35L requires more power to actuate the flasher module as it did not work with the Philips Unltinon LED bulbs I purchased.

I wish I had a multimeter here with with me so I could gather more accurate data, so apologies for the informal account of my experience.

Happy Trails!

 

We’re is the turn signal location?
Stuck my head under the dash and did see anything,
Is it on the back side of that fuse box?

Thought about installing LEDS

 

yes, backside of the fuse block in the cab. I used a mirror to get the approximate location, and went at it blind.

 

Back side of the fuse box under the dash. You’ll have to unbolt it to access the relays.

 

Ok, so ended having to remove the upper and lower dash panel and the plastic vent tube that comes over the fuse box
To get to it,

So I put the LEDS in front and back with the Novita EP35,

The rear LEDS work just fine with a normal flash rate BUT NO lights up front for the flashers- blinkers.

If put in the incandescent bulbs in the front it works perfectly with LEDS in the back.

Do I need a different flasher?
