Here is a picture of the half done fog light test fitting. Still brainstorming about the type of LEDs or bulbs to use. It's best of both world: It's cheap DIY while getting what I like :D

Now to think of it, still debating about wheter to mount with three srews to expose the corner or put three LEDs for hilight and mount it using hidden screws inside. Anyway, I will post my final result, now only if I can find a dual bulb holder ;)

Thanks, I missed your post...I actually went for the black look with RX8 on top. My avatar was a friends I did.

It will be nice to see the final version - i heard that the application of the rear fog light was quite complicated

As it is not an option for Australian model I have the light ship from Japan (Mazda JDM)

I have mine install by the mazda dealer today. It works wodnerfully. Have the DSC button changed to a dual fog light/DSC off (each occupy one half). The wiring is pain. They have to strip off the steering coloum casing the dash board. The front panel (driver side) wire the thing thru the driver side door. thru the boot and have the rear bumper off to wire and cut.
Fortunately if have factory made ALL bumper have bolt sets that ready for fitting (no drill required) ~ Well except the cutting of the rear triangle

Takahashi -

Can you tell me please where exactly they cut the rear triangle? I got the same JDM light yesterday, and went to install it today. Problem is, it looks for all the world like the foglight is too big to fit through the triangle!

I wasn't brave enough to start cutting until I posed the question on this forum... where exactly do you cut? The inner edge (around the diameter) of the triangle?

Finally, can you please post a close up pic of the fog light? All the pics I've seen so far have been from like 15 feet away. I need a close up to see how far into the cutout the light sits.

Thanks!

takahashi
11-21-2003, 07:49 PM
Did you have the instruction book to come with the lights?

I saw in the instruction book (not with me - still in Mazda dealer - I was going to pick that up Monday). It said that you cut the most inner bit of the triangle from the inside - hence you have to take the bumper off. You still need the inner side of the triangle for supporting the fog light.

If you want the installation booklet I can scan it on Monday or email you a photocopy if you like.

Yes I have your email...

I think you need a Japanese - English translator as it is in Japanese. Anyhow - the pictures say 1000 words in the booklet and even the Mazda mechanics can read (no offense).

AND yes I think $A200 for labour is kinda cheap :) (I AM F'ing HAPPY)

Still waiting your 6 stacker right... not too long I suppose.

11-21-2003, 08:56 PM
so its 200 for mazda to install

11-21-2003, 09:01 PM
Not to worry Steve, I'll figure it out.

Mike, that's $200 Australian.

mikeb
11-21-2003, 09:04 PM
ok so how much US for install and fog light?
did you get it from canzoomer

Omicron
11-22-2003, 01:04 PM
Yep. The light itself was like $88, as I recall, and comes with nothing but the light. No idea what a dealer would charge to install it, but most likely a coupla hours of labor.

Depending on how you wanted to wire it, you might also need to get the Mazda factory switch, which is about $35 from CanZoomer. Or you could use your own, if you're comfortable tapping into power from somewhere, then running it to the switch/light. I got the factory switch, but may not use it. Initially I plan to tap the rear fog into by rear brake lights, so I have a "low mount" brake light. Think that'll be kinda unique, and will save me a lot of wiring effort. If it's too bright for that, I'll try to get a lower wattage bulb. And if that still doesn't work out, I'll wire it to a dash switch. We'll see.

Problem is, it didn't come with any instructions, and I wasn't willing to go cutting on my rear bumper "underskirt" till I knew for sure it'd fit. Takahashi is going to send me some close up pics of the install, and email me the installation manual. It's in Japanese, but I think I'll be able to figure it out from the diagrams.

I'll keep you all posted.

11-23-2003, 03:10 AM
Nice! So now a question. That looks like a single filament bulb. If you're going to mate it up with the running AND brake lights, won't you need a dual filament bulb? One filament illuminated with the running lights, and one with the brakes... ?

seikx8
11-23-2003, 11:44 AM
I used two bulbs -- I can't find any dual filaments bulb holder that will fit. Was too embarrass to took the ghetto picture (The secondary bulbs was tied by wired to the holding metal piece) :D Anyway, my next upgrade will be using 168/194 bulbs which mean I might need to pay visit to the junkyard :p and I have to worry about water getting in there. Prior to that, I was thinking about building a circuit to controll the brightness, but it was too much work.

With some luck I might be able to get the picture with it on tonight.

seikx8
11-23-2003, 07:27 PM
Remove the rubbers and pass the wire through. It's easier to pass the wire through and pull it our via the license plate light opening then pass the wire down from that license plate light hold. When done install back the rubbers to protect the wire. . .

Hook up the wire to the fog light . . . For the EOM fog light, there is bracket which will fit in those poles with self tapping screw I believe.

11-23-2003, 07:50 PM
Guess the .avi file didn't work due to its size. Anyway, here is a peak at the method mounting I use. As you can see, I use two 5w bulbs on the two side and a 8W bulb in the middle. So there you have it, for what it worth I spent less than $50 ;) Around $10 for the bulbs and holders and reflectors which I pickup from pepboy. A piece of aluminum which I have left from last time I made an intercooler probably cost < $5, plus some MIG welding with my broken gas regulator which you can see the horrible aluminum welding. Plus a small bottle of all purpose metal polish compound for around $25 and some sweating into those aluminum polishing and installation which is priceless :cool:

Whether it come out good or bad, I do find myself enjoying the work and finding little interesting thing how the car was made.

Sure it can stay on if you want to. You can wire to turn on by a switch or have multiple bulbs and combine those as you want it to function. In this case, it function as a break light as well as running light at night.

11-25-2003, 01:01 AM
As for making it for sell? I doubt it will make it in the market since I have no plan on marketing. Maybe someone will be inspired enought to start mass producing; especially the aluminum polished pieces can be cut and mass produce. ;)

i want to get some type of light down there...even if it's just a red LED that's spliced into the running lights

My thoughts: I'm not too fond of the big aluminum thing, so I was wondering if some other system might be rigged up with a bit of lexan / plexiglass, some reflective "chromed" plastic and some red LEDs (since I've been installing the "stealthed" bulbs everywhere else, I wouldn't want to deviate). I reckon you could tap the same wires for it and run the LED.

If I can get time in the next week or so, I'll see if I can come up with anything.

nicely done romulus...thats more the route i want to take
don't like the full aluminum piece that some put in, but i'm not convinced yet i like the fog light down there

i'm almost thinking something indirect, a nice glow without even seeing the bulb or LED itself...but since that piece back there is solid, that might not be an option without getting clever...but thats where all the fun is, right? :D
