Question for Folks Running Full LED's

[Already Gone]

I want to put LED's in my 1972 C10 truck for all the outside bulbs, except headlights which we be upgraded but not LED. In the original fuse panel it shows 1 flasher for signal lights and one for the hazard lights. Do I have to replace both flashers with LED flashers so the hazards will work as they should, if I need them, or will just replacing the signal light flasher be sufficient.

I just had to replace one with a No Load flasher on my 72 . I got it from NAPA .

I replaced both of mine to make them blink right and not be slow are fast depending on what manufacture bulb you use.

Some LED lamps have a shunt load built in so that it's enough draw to run the blinkers; the safer bet is to get one that works with zero load.

Read the package to see what kind of sound it makes though - maybe a full digital one beeps instead of clicks, I'm not sure what happens if there's no physical relay.

I am thinking of running pair of these.

That is the one I replaced both mine with. Works great with all LED.

[flashed]

That looks like the same one I used .

I just finished this same endeavor and it was a pain due to my lack of knowledge with electrical work. If I were you I would do both electronic flashers and make sure you have the reverse polarity adapters in case you have to use them (I did). The biggest thing is making sure you ground your front parking lamps well! Ground your flashers well too. Make sure you grind down to clean metal when grounding all your wires.
