hi

Just fitted some JTX lights, work well, amber fashes alittle fast, was told to get a gadget now to slow down the blinker, Super Cheap have a Calibre LED Load Resistor 25watt one
I have seen cant remember were, a fellow un did a cover the a blinker unit and took out a resistor which slowed down the flashing, but for the life of me I can not find it.

any other way to slow it down

I do indeed sell original Toyota flasher modules that I modify to flash the correct speed with LED blinker bulbs. See the link above.

I have some questions though. What are JTX lights? Where did you install the load resistor in the circuit?

I have lots of strong opinions on this stuff which is why I started modifying the original flashers in the first place.

1. Installing a load resistor defeats the purpose of installing LEDs. LEDs use much less current, saving electrical load on your system … but then the load resistor just sits there soaking up current and turning it into heat. You’re back to square one using up just as much current as an incandescent bulb. You’re losing the primary advantage of LEDs.
2. Yes there is a mod described on this forum where you cut out a 100 ohm resistor from the circuit board inside the original flasher. Yes it works. I think it’s a pretty dubious solution though. First of all that’s the electrical path for the hyperflash that lets you know when a bulb is burnt out, so that won’t work any more. Second, it increases current flow through a transistor inside the flasher. Those transistor are out of production now with no known substitution. Do that mod at your own risk - you may find that you shorten the lifespan of the original flasher module.
3. The circuit inside the flasher is a basic oscillator that triggers a relay. Oscillator circuits can be tuned to run at different speeds in a stable fashion. That’s what I do. I don’t cut out a resistor. I use high quality Panasonic and Nichicon parts - not junk. If you want the secret sauce find a circuit book that covers various oscillator designs, it’s all in there.
4. I’ve bought several of the cheapo flasher modules, and a couple expensive ones that turned out to be repackaged cheapo units. Absolute dumpster fire construction inside. The lowest quality components (prone to early failure), flux all over the PC boards (which can become conductive over time and cause shorts), very poor soldering (prone to cracking from vibrations). What does that mean? They’re probably not gonna last very long. Maybe some do and that’s great, but it’s going to be hit and miss. So what, keep buying a string of $15 units over and over? The originals have lasted 30-40 years at this point, proving their worth - why fight upstream against that? Just modify the oscillator the right way with good parts and keep it rolling. The relay in every one I open looks like it just left the factory, no signs of arcing or flash welding. They are seriously robust units, Toyota put in a relay that was overkill for the job - but that’s why we buy Toyotas.

I haven't installed any load resistor as of yet or any thing else, was planning on buying another original blinker unit before removing and modifying the one under the dash, thou there are units here we get from Super Cheap Stores or Repco called ( Calibre LED Load Resistor ) and ( 12V Load Resistor In Blister Pack Of 2 - LR12/2 ) and another from Repco ( Narva Electronic LED Flasher 12V 3 Pin - 68245BL )

also found some rules about these lights in Australia and I've asked JTX for there information on the set rules as well

Quote from JTX web site, JTX lights are designed to meet ADR requirements for headlights, meaning they are legal for use on Australian roads, provided they are used in accordance with the rules.
Colour Restrictions:
The ADR rules state that only white and amber colors are permitted for forward-facing lights (headlights and indicators).

Ok that info helps. JTX are headlights - that’s the first time I’ve heard of them. Hopefully those lights don’t get you flagged … what do you call it down there? Rego? Anyway, those won’t affect the blinkers at all.

If you end up wanting the module I sell give me a shout. My website doesn’t have shipping to Australia but I can arrange it so you can order. If not, no worries and good luck.

All depends on shipping cost, this is the front end of mine with the LEDS in place

My brother picked up a set of these today from Super Cheap for me, going to give them a go, but really I do like the idea of having less gadgets and using just the blinker unit relay.
