Re: Led flashers

There is one flasher for the turn signals to work, and another flasher for the hazard lights.

Re: Led flashers

Yeah i know the other flasher is for hazards. Same ? - do BOTH need to be for leds for either to work ? I'm guessing yes.

Re: Led flashers

If you are using LED light bulbs, you can replace both hazard and turn signal flashers with flashers that are compatible with LED bulbs, in order for both your turn signals to work and for your hazard lights to work. Or, install load resistors into the wiring so you can use standard flashers with your LED bulbs.

Sorry, I just re-read your question and I'm not sure what you mean "for either to work." But I think you mean will the turn signal work properly by only replacing the turn signal flasher, and I believe the answer is yes. So if you are only concerned about turn signals, and not worried about the hazard lights working, then just replace the one flasher. I think it is common for most people to replace both flashers at one time, with the same part number flasher. The one that I have seen people endorse here on the board is the 2-prong electronic type with a ground lead pigtail.

Here is one: https://www.amazon.com/dp/B01GIU9M0Y

Re: Led flashers

Ok now we are on the same page. I had only bought one flasher, like a dummy. Turn signals light but don't flash. Reversed polarity on one flasher and drivers side gets bright when turned on but still doesn't flash. I'll get a second flasher today and go from there.

Hmmmm that sounds weird...it should work on turn with only the turn flasher in...I would have thought by reversing the polarity that would solve the issue...I would think in this case either the flasher you chose is giving you issues or there is some other issue. I'm guessing you have leds in front and back? Almost sounds like a poor ground.

Re: Led flashers

I now have both flashers made for leds installed. Problem solved, both led turn and hazards work as they should. Found one "bulb holder" in dash that wasn't making good connection. Right turn signal indicator. Sanded prongs that hold bulb and it works although intermittingly. I don't see those bulb holders in parts catalog. Where can i buy a couple ? Tks for all the help. Leds look cool/bright.

Re: Led flashers

I got one at Advance Auto Parts. It was about $8, I remember not liking that price very much. I think they are widely available online too. Here's one at the bottom of this page

Re: Led flashers

If you have a gauge cluster, then your Temp light is probably unused, and you probably have a bulb holder in that position. That is your spare bulb holder.

Re: Led flashers

I've got idiot lights, no gauges. Are the bulb holders available anywhere?

Re: Led flashers

Well since I got one for a high price at Advance Auto Parts then I think they may be available at other car parts stores also. If you don't find it locally, order some on eBay, Amazon, LMC Truck, etc.
