Flasher relay for LED blinker lights

Rdx bulb

Ordered it. Will let you know when how it works installed. Thx you all.

Rob

Doesn’t sound like a flasher issue to me, but I’ll learn something new if it is!

Please post your results.

I am not sure if this is an led issue or not. Before I started work my my d110 the turn signals where not working. I have since done an ls3 swap with Dakota digital gauges. All of the lights work when the hazard switch is flipped so I know they are wired up. But when I use the indicator lever nothing happens. Also have all leds and an led relay switch. Would I need to install load resistors or is something else going on?Thoughts?

If nothing happens, it is a wiring issue and you will need to trace the fault. Possibly the signal switch or hazard switch or a bad connection. Start with understanding the wiring schematic and go from there.

Load resistors are for a different issue (both sides flashing) and are a poor bandaid. There is a proper fix available for that issue.

10-4. Will report back. I have been going through the wiring diagram. Haven’t found any problems yet.. Signal switch on the steering column? I have replaced that and have checked to see if that was the fault. Thanks

Yes, the column switch.

The basic gist of the system for the turn signals.

Fused, switched power goes to the hazard switch. When the switch is off, power goes through it to the flasher relay. The output of the flasher relay goes to the column turn signal switch. From the turn signal switch, it goes directly to the lights.

First check the fuse... The hazard switch when on uses unswitched power from a different fuse. The turn signals use ignition switched power.

If you replaced the turn signal switch, check the connectors.

Check if the hazard switch is passing power to the flasher relay when off. This is the light green wire with no trace. Switched power in to the hazard switch is green/yellow.

I have confirmed that the hazard switch is not passing power to the relay.

UPDATE Turn signals work great

Update

Took Red90s advice and took out the turn signal dash indicator last week for a short term fix. Turn signals worked great. Ordered the bolt on bits grounded led bulb. Installed today. Signals work perfect. Very happy!

Thx for all the help guys

I got in the new replace hazard switch last night. Plugged it in and it works! Simple fix. Thanks for the help!

I just installed all LED lights on the exterior of my vehicle and I am experiencing the common rapidly flashing blinkers. From what I gather, I need a relay and resistors. I'm completely illiterate when it comes to electronics, are these pretty easy to install?

That flasher won't work, wrong pinout. Get the wipac flasher from rn, ab or whoever. Do flasher first, you may not need the resistors.

No, you need either one or the other. "Old school" relays work by using the current drawn by the lights to heat up a heat-sensitive element that would cut out after a second or so, thus causing the correct flashing rate. But LED's use a lot less current, so they don't work correctly with the old-fashioned "thermal flasher" relays.

You can fix this one of two ways:

-- Put in a new-style flasher that works at the correct rate regardless of the current drawn by the lights, or;

-- Splice in a resistor on each side to increase the current drawn by the LED's, to essentially "trick" the flasher into acting like it is still flashing old-style incandescent bulbs (because the resistors increase the current draw so much that it looks like an incandescent bulb).

Load resistors will work as well, but they are crappy way to solve the issue.

They kill you on that thing now, geez $50 shipped. When it first came out they charged me $5

All you really need is a couple of diodes if you want to spend less. Maybe I should sketch a circuit.

As mentioned earlier, get the RDX relay from Boltonbits. It is the only one that ensure everything works properly.

Thanks for the sketch and for the detailed responses and, much appreciated!
I lean towards the Bolt on Bits part, is this the proper one? https://www.ebay.com/itm/RDX-repari...0tdi-300Tdi-/232613852750?hash=item3628ddb64e

Here is what is needed to properly fix the indicator crossover issue if you do not want to spend the money on the RDX indicator.

Green/White is the right signal wire. Green/Red is the left signal wire. Item 64 is the flasher indicator light.

Cut the two wires in the loom near the warning light cluster connector with enough space to add in the required connections. Add a diode to each wire and join the outlet of the two diodes. Connect that to one side of the light. Connect the other side of the light to ground. 1 Amp diodes should be more than adequate which should be 10 cents a pop or so.

Here is an example: https://www.digikey.com/products/en?keywords=641-1310-1-ND&pkeyword=641-1310-1-ND&v=

Yes, that is the part for fixing the crossover issue. That does not fix the flash rate issue. For that, you need this: https://www.ebay.com/itm/RDX-4-Pin-...der-/231258888157?vxp=mtr&hash=item35d81a97dd
