Find out what kind of load you're looking at. If the switch is rated high enough, just use a switch. The relay would be necessary if say your tails pull 12A (just a random number) and the switch you have only does 5A for example.

I would like to do this too, I've thought about it and it really shouldn't be to hard. BTW this thread is great, I didn't know so many of us street raced in Mexico. We will have to get together down there sometime.

It looks to me like the load for the complete tail light circuit would be pretty high at times. How would I figure out the load?

Circuit analysis...although you could just always use an ammeter at the point where you wish to put this switch in as well

I could see this being useful to maybe recover your car if it's stolen. A cop is going to be more likely to pull someone over with no brake/tail lights. Park you car and hit the switch, if someone steals it he's gonna have no idea he's tail lights are out.
They say if your ever kidnapped and locked in a trunk to try to access the tail light wires and rip them out.

Yet another good use for this.

I'm planing on doing this this upcoming week when I install my nitrous kit.

Ok, a little update. Today I got the remaining parts I need to install my Nitrous system and I'm planning on installing it this weekend. I'm gonna do this mod at the same time so keep your eyes open for a "How-To" thread with pictures and video early next week.

i've used the parking brake. it sets off no lights. when you dive onto the regular brakes with heavy front bias, its hard to miss the car pitching (even with suspension mods). when you hit the rear brakes, it has a tendency to keep the car flat.
you have to know how your car is going to react to yanking it up at high speed before attempting it (testing it at different speeds until it just about locks up the wheels to get a feel for it).

No update yet, I've been busy with college, work, APS, installing my HIDs and my new fog lights. I should have this done this weekend though, I hope.

I would think that would wear out your parking brake really fast, and new shoes aren't cheap.

Besides, mine doesn't grab well enough to slow the car down that quickly.
