    Led bulbs

    Changed all bulbs to led bulbs and put electric flasher in now I don’t have turn or hazard or brake lights.what did I do wrong

    The electronic flashers which direct-fit into the 2 prong socket require a certain minimal amount of current flow to operate their own internal electronics. Since the path to ground goes through the bulbs, when 100% of the bulbs are LED, some of the flashers just don't work.

    To prove this, swap any one of your light bulbs back to incandescent and verify that the flasher flashes. If it does not, the flasher itself may be defective.

    There are flashers which are sold that have an extra dedicated ground wire, and those ones should work when 100% of bulbs are LED.

    Are your cluster indicator bulbs also LED? I'm surprised those aren't enough to let it work, if they aren't LED.

        EL-12 is the direct swap electronic flasher. It does still need one bulb or a resistor on each side to work properly. Otherwise I think you would need one of those 2 prong flashers with the added wire and ring terminal to tie to chassis ground. I don't remember which model flasher that one was. EL13 maybe?

        But yeah, if nothing flashes, try putting one real bulb back in and see if it works. If so, add a "LED swap resistor" to each tail light or front blinker. That should sort it.

          I have not had to buy one to solve this problem, because I keep incandescent bulbs in the front turn signals.
          This is just an example, I realize .ca is not the right Amazon for you, and I'm also sure there's a cheaper one somewhere else: https://www.amazon.ca/United-Pacific.../dp/B075G5XX5K

          The basic idea is that rather than grounding its internal timer circuit and relay through the lighting circuit through the bulbs, it grounds those functions through the wire, so the relay just toggles the circuit on/off, which should solve your problem. Sly is also correct that a resistor should do the job as well, if there's a spot you feel like mounting and wiring one in, and maybe you already have a baggie of them because Amazon only sold them in a 10-pack when you needed 2 for a project, 10 years ago. I know I do lol.

          I have bought the Scott Drake adjustable electronic flasher a long time ago when I was trying to tune my sequential turn signals to my liking, and didn't really end up liking the flash rates it offered, but it does work for this application as well as it has the extra ground wire. https://www.summitracing.com/parts/sdk-stlevf13350

            yeah... that's the flasher I was thinking of... that United Pacific 90650.

              and people wonder why my cars still run original type bulbs and thermal flashers like they were built with 40 years ago.

                Yeah... but with the way people drive around here... getting as much light as possible coming out of those old dull tail lights saves my neck from further injury. Kinda why I did it.

                  Yes the substitution of a two prong electronic flasher with a ground pigtail is the easiest option that should work just fine.

                  Same as Sly just 1/2 price

                    Put led flasher in it works but my right side arrow doesn’t light up in cluster it worked before and still no hazards or brake light's. Went under dash checked wires and found one unknown black connector with male pins and don’t know where it goes

                      That looks like part of the brake light switch stuff.

                            The arrow in the cluster may be bad timing bulb burn out. The hazard flasher is on the back side of the fuse box. So yeah, need 2 flashers.

                              Led Bulb is good switched and worked.do I need a led flasher or a regular flasher for hazard?
