TST 2 Pin LED Flasher Relay Gen 2

Super fast installation. Maybe 5 min. Works perfect.

Advantages: Easy install

Disadvantages: none

Fits perfectly on my 2008 Kawasaki Ninja 650R (even though my model year isn't officially supported by TST) and works as advertised. Huge range of frequency adjustment.

Advantages: Much simpler and less destructive than splicing wires to fit any other "universal" relay. There's not a simpler solution for LED turn signal retrofits (for applicable bike models).

Disadvantages: The stock relay flashes on-off-on-off-... whereas this one flashes off-on-off-on-... Basically, this means that there's about a 3/4 second delay between toggling the blinker and seeing light. I suppose it's not a huge deal if you're used to signaling well before changing lanes, but I see it as a potential safety issue if a sudden lane change is to be made.

It doesnt get any better than this.
Seat off, old relay out, new relay in, seat on. Done.
No lamp error lights on dash, hyperflash is gone, switchback turn signal continue to function. Great price for ease of installation and functionality. Using heat producing resistors is for chumps compared to this approach. Pretty much perfect.

Advantages: Ease of use
Engineered well
Simple

Disadvantages: None

I mean, I guess it works. Lights still flash fast a few times before slowing down. Wouldn't have bought had a read that ANYWHERE in the description.

Advantages: It eventually slows the lights down.

Disadvantages: As stated above, the lights still flash fast a few times before slowing down. Asked support if this is normal with stock front directionals and LEDs in the rear and was told yes, and even replacing the fronts won't fix this. Looks pretty crappy to have them blinking fast then slowing down. Would not have bought had that been in the description. Waiting to hear back if there's any fix at all for this issue.

Our LED Flasher Relay does have a momentary rapid flash that is caused by an internal capacitor needing to charge on signal activation. This rapid flash lasts for less than 1 second and may present itself after an undisclosed amount of time depending on the bike and the other equipment on the bike.

Super simple to install and fixed the rapid blinker right away!

Advantages: Very quick to install and fits like OEM on my FZ-07

Disadvantages: N/A

Super east and fast install on mt-07. Had my back led lights with resistors and front without and still made everything blink exactly the same rate and brought the front lights back to normal speed

Advantages: Easy to install, adjustable flash rate. No extra wires to try to hide like other brands.

I have a 2003 Yamaha YZF600r that I upgraded with LED headlight, rearview mirror, flush-mount, and tail lights. Although my bike isn't listed for this, it replaces the same part (4MY-83350-01-00) as other bikes that are listed (this part is VERY common... apparently).

By far the simplest solution to my hyper flashing issue. The other option involves trying to stuff a bunch of resistors in impossible spaces and mounting them in ventilated non-plastic areas (bleh!).

Advantages: Took 21 seconds to install and IT WORKS!

Disadvantages: Be careful when removing the housing to adjust the flasher timing. The board that the pins are connected to is not attached to the red piece as the picture(s) might suggest.

Nice plug and play solution for hyperflash - no brainer.

Advantages: No soldering or splicing wires!

Disadvantages: ***Bought for 2017 CRF250L***
I'm not sure if this is peculiar to EU/UK models, but there is a water-tight rubber boot which the stock relay fits into. This replacement is much thinner and thus the boot does not fit around it and would not prevent water ingress. I ended up wrapping many layers of electrical tape to approximate the diameter of the stock relay so that the boot would be a better fit.

Now that I write I do notice the "E" model has the correct shape, but has 4 pins, which is 1 too many for my bike...

This is an amazing little plug. Very easy to install and way cleaner than having a bunch of relays hanging off the bike. Highly recommend.

Purchased with integrated tail-light and fender eliminator kit. Simple to plug in and the installation videos made everything a breeze. Worth every penny and more!
