Quite Ferocious? Actually Obedient? ZX12R Head Cover Gasket Replacement, Shorai Battery, Highsider Turn Signals, and More

I’m all excited about getting a new toy.

Sorry, this is from yesterday, October 10th.

The turn signal relay arrived quickly, so I’m going to install it.
The Daytona LED turn signal relay is absolutely recommended.

How to choose electrical accessories. Smart and easy installation

It’s truly become a wonderful age.

Such convenient items were surprisingly rare in the old days,
and there were times when we had to cheat by adding resistors.
Tasks that used to be tedious are now, especially in recent years, something you don’t have to think much about
and can be installed easily—it’s a wonderful age.

There’s no reason not to use such amazing items.

What’s amazing is the OEM-style rubber mount! And it works both vertically and horizontally

The mounting rubber that fits into the tabs is included.
It works in both vertical and horizontal directions, so installation is no problem.

In other words, you just remove the OEM turn signal relay and swap it out—very easy and simple.
The turn signal relay that’s installed isn’t secured with cable ties, is it…?

If it’s a 2-pin turn signal relay, it covers everything.
It also works with 110 connector types. You can remove it and plug it directly into the 250, so it looks very stock.

The ZX12R is quite challenging to reach the turn signal relay

Since I removed it the other day, I’m now familiar with accessing it.
The turn signal relay is hidden in the box on the left side of the image.

Just remove the OEM one and plug it in the same way.
It installs beautifully with no sense of incongruity.

Rather than focusing on price, it might be better to choose items based on how cleanly they can be installed.

I’ll tell you everything. This turn signal relay supports up to 100W.

It supports up to 100W! Let me say it one more time: 100W!

You might think “I don’t need 100W anyway,” but you do use hazard lights, right? Hazard lights.
In other words, this turn signal relay alone can also function as a hazard relay.
If you currently don’t have hazard functionality, just switch to a hazard-equipped switch and you’re good to go. *Left-right conduction type

Right now, I’m exclusively using Daytona LED turn signals.
If other manufacturers’ turn signal relays are installed,
I tend to replace them without exception, so please understand (*´ω`*)
