The flasher! Flashing brake light

Maybe it annoys you, that's probably a good thing as it means it got your attention.

This is an install of a flasher module for the high mount brake light in the civic wagon. And subsequent install of a resistor to get the light to work correctly.

I won't go into the removal of the trim or light itself, it comes apart pretty easy, just watch out for breaking the plastic tabs, I did on one and am now just using some double sided tape to hold things in place.
So first off with all things I can out some LED lights in, I put em in.

Next we want to add the flasher module. It's pretty basic. Split your positive wire, one end goes to the lights the other end goes to the plug socket. And just tie the ground into the black wire.

This worked great when the power was off. Turn the headlights on though and I guess there's enough residual juice to dimly light the LEDs. Since the flasher module triggers on any power at all that means you turn the car on and they flash once, but are on dimly the rest of the time. They do get bright when you step on the brakes, but no flash.

That led to the purchase and installation of this resistor. Since the resistor heats up you don't want it directly against the plastic parts. So I needed to find somewhere to tuck it. I decided since I have a pop rivet gun to use that. You can also use a self tapping screw though it won't sit as flushly as the rivet head.

If you are using a rivet open up one of the holes big enough to get the rivet through. If a screw then just a small pilot hole in the metal on the car should suffice just so you get stuff lined up easily.

And popped. Tucked it away in there. It'll have some breathing space but is close enough that I don't have to do any additional wire splices.

Next thing I did was to splice it into the red wire.

As well as the black.

With this type of resistor it bridges the wires to draw off some of the juice and then dissipates it as heat. In very rough terms. This way the led isn't getting whatever little trickle of amperage it was that was lighting it up initially and then when it gets full power from the brake lights it's enough to kick them on and activate the flasher.

And here are the results.
