how do i set it up where it would stay on when i turn on my headlights and then when i hit the brakes, it would light up brighter like the rear tail lights?

please help professordave! i am terrified of wires =X.

Shoop, I don't think the EVO-R light can do exactly that. I think you can tap the solid on lead to the Red wire in the harness (assuming you have an 09 or 10 Z) to come on with the tail lights, and then connect the flashing lead to the brakes (green wire). That way, the light would look brighter and flash if you hit the brakes while the tail lights were on.

Hope this helps!:tiphat:

Is that all you need from the old fog (dummy light) that backing plate ? If i was going to install this on a new bumper. One that didn't have the old fog would the backing plate be the only thing i'd need to get extra ? Thanks for the help and a great write up rep to you:tiphat:. Would you happen to know the voltage range the new led fog you installed can handle ?

Thanks!
Technically you don't need the backing plate, but the center of the valance is pretty flimsy without it. But yes, that is the only part of the olddummy light that gets re-installed.

I know the light is 12v, but don't know what range it can handle. I'd PM Jay over at EVO-R (check the vendor area, or the Exterior/Interior thread for one of his posts). If you get an answer, post it here:tup:

Yes i had sent him a pm last night. I'll post any info i get thanks for the help and the great diy...

:tup: Thanks again!

Yeah, Jay can be a pretty busy guy, but he always does respond.

Just curious, what are you hoping to do with the light? More voltage? Less?

Maybe it's a surprise ?:stirthepot:

If the light can take a little less voltage, then i'll be able to hook it up like this. On when the taillights are on, brighten up when you hit the brakes and flash when in reverse.

I'm pretty sure someone (one of the first to receive the light, maybe?) hooked theirs up to a 9 volt battery to demonstrate how it worked. Are you hoping for the ability to use even less voltage than that?

If the 9v to 12v difference is noticeable enough that will work just fine.

I need to ask the factory who made the PCB LEDs for me.

Thank's for the reply:tiphat:, i'll be looking forward to their answer good sir.:tup:

If you can get this done let us know! I will send rep points your way. =)

That will look great! :tup:

I've found that the light is a bit dim in daylight (which makes sense of course - since it's meant to be a bad weather safety light). So connecting them to the taillights for the solid on (if not connected to a switch) sounds like a good plan.

Sharing my experience on the DIY
 

Not sure if this has been mentioned, but on my '10 Z Roadster, the brake was green, but power for parking lights (LEDs on when parking lights are on), the color of wire was actually purple. I attached the leads from the fog light to the driver's side rear taillight harness. Also, for people wanting to remove the troublesome dummy light, I found it easiest to use a Dremel tool. At first, I was going to create a slit in the stud to hold that steady to turn the nut, but then realized that the longer I use the Dremel tool to make a slit, the hotter the stud became, and eventually just melted the plastic. I say, why waste time struggling with those nuts when you can just melt the plastic? Anyways, I wanted to share this experience with others that are going to install this fog light.

Thanks xinlee. Good tip re: wiring colors on the roadster. Also, I wish I had tried the dremel tip. I removed my dummy lens before I received the EVO-R light and thought I might have to reuse the mounting screws. So I was trying to be careful. The Dremel approach would have saved me a lot of trouble!
