Question Can you rewire the headlights to open when you flash them?

As my S5 vert is now running again i want to start working on some details. One thing that keeps bottering me is that the headlights don't open, if you flash with them. Only the FTP-Lenses will light up.

I had a 323F before which would just open the headlights, flash them and then close them again. I would like to have the same in my RX7. Any idea if (and how) this can be done?

Not sure but was thinking maybe if you somehow grabbed the relay for the 323F to FTP you might be able to incorporated it into the system. The Flash to pass right now is through the dimmer relay.

or you could just flick the headlight switch on and off real fast with the original setup.

Same as using the headlight switch to do that.
If you wire up to flash and pop up, it'll do just that flash and pop up. No lights unless you hold the lever back. So, it's the same as using the headlight switch.
Flash to pass lens is actually bright ...IF lens are clean. Just wet sand those things and wax.

Really unnecessary wiring.

FTP is done with the hi beams, so flipping the light switch wouldn't produce the effect that i want.

I will have a look at the wiring later. thanks for the grafik...

First I'll attempt at answering your question, then respectfully suggest you don't go this route.

In the wiring diagram above, you essentially want to tap into the headlight high beam circuit and feed it to the bottom middle connection shown on the "retractable relay in cluster switch", where someone edited a line in the picture.

A few reasons not to though:
- you're doing an unnessary mod without much gain (IMHO)
- you could mess things up, and these circuits are bad already (I'm thinking S4, so maybe the S5's are better)
- you'd need to _hold_ the flasher lever while the headlights are going up then release, so you're not really 'flashing' the lights, you're turning on the high beams and raising and lowering the lights. And you cannot do the 'double flash' this way.
- more work on the motors

I don't think the motors are worse than the one from the 323F and these ones worked for ages.

But the second note is interesting. If I remember correctly, the 323Fs Headlights stayed open 2-3 seconds so you could flash them. I think i have to look for the wiring diagram for it and look how they done it.

I'm not sure that "how someone else dun it" is going to be of much use...you're biggest constraint is the oddball switchgear you must deal with and it's integrated relay.
I'd suspect the best approach for an optimal outcome would be to suss out the switch diagram and see what conditions must be met to achieve your goal and then see if the switch can be modified to make those connections.

Why would you want the lights to come up for FTP? That necessarily is a lot slower than the factory arrangement using the FTP lenses - and if someone doesn't see the FTP lens flash, they likely aren't paying attention anyway.

That's so vile to have the lights pop up when Mazda took the effort to cut out bumper lenses for that purpose. Sorry man buts its just ****** gay. Leave them alone.

I don't know if it's "****** gay", but it is pretty inefficient. It's going to take longer to open and close the headlights, and as mentioned already, the high beams will already flash through the FTP lenses as soon as you light them up... However then the lights would raise, giving a semblance of double flashing? Anyways, pfsantos and VANHALEN are right, that's a lot of unnecessary wiring through old as **** harnesses for a trivial cosmetic mod.

You realize that the headlights have to come up all the way,while on, then hit the limit and go back down..and shut off.
The Rx7 system doesn't do that,and with the wiring already inferior you will be getting into some nasty ****.
This mod is gonna be more trouble than what it is worth.
Flick the HI's on the switch and pass the Dude..

The wiring isn't inherently "inferior"...it may be degraded due to time/exposure but it's not of lesser quality.
The design of the system and the integrated retractor relay are what make this impractical.
You could design a system to do exactly what the OP wants but I think you'd have to ditch all the stock wiring, relays and switchgear to do it.

The strange flasher lever seems to be the biggest problem. I don't know if i can rewire it to work the way i want. I will start to look for a used one, so i can play a little with it.

this thread is dumb.

takes too long to flip up the lights and will cause additional wear and tear on the headlight motors for what? the same purpose the FTP lenses provide...

i almost feel proud that mazda even gave us FTP lenses for this purpose and people want to go and **** it all up.


if your real intent is to blind someone to get their attention, you could always get a redneck light bar and weld it to the roof.

I don't know about anyone else,but by the time the headlights come up all the way I am on the other side and around the car already.

i second that, i'm too impatient to ever use my pass beams. the only people who ever use them on the road are ********* anyways.

socker mom: "there's some ricer behind me flashing to go by..."
socker dad: " screw that little jerk, don't let him pass!"
socker mom presses the gas pedal on her prius
ricer FC is left losing ground
ricer FC is left behind by the 60 mpg econobox and pulls off at the next exit simply out of shame


yep

and the FTPs mellow out the light anyways versus attempting to blind people with your high beams, to me allowing it to be acceptable in stock form.

yeah okay, maybe it's dumb. But for nearly every modification you can make, you find people that find it dumb. Big Spoiler? dumb. Giant Soundsytem? dumb. 20" Rims? dumb.

Anyway, it's a modification I find usefull. I'm not someone who uses his FTP-Lights 20 times a day, but when I use them, I want other people to see and recognize them. This is exactly the reason , why hi beams are used for FTL in most cars. If I use them the way they are now (stock) people don't recognize them and I don't like that.

So I will try to do it. This will take more time, as it isn't the easy modification I hoped it would be, but I will try anyway...

In the first gen forum there is a thread about it. Basically run a diode from the highbeam wire after the switch to the headlight up wire after the switch. Or from the ftp switch. After the switch to the motors.
