Default A light idea.

So I found this thread because I to have mounted my 9500ix up high and discovered that the display's auto brightness sensor is not really in a optimal location. I checked and the sensor is not feasibly relocatable. So if you can't bring the sensor to the light, bring the light to the sensor !

I'm going to pick up some 1/8 or smaller clear acrylic rod and bend a 5" length to mount along the upper side of the case. Going from where the laser detector pod is at, along the crease, and terminate right at the "vents" above the light sensor. The front end (light in) will be curved up towards the window. The back end (light out) will be curved down. If the proof of concept works ... I'll extend the light rod (thick fiber optic cable) down to the emitter.

I can cover it in aluminum foil (to reflect light in and mitigate light loss) and then shrink tube it to make it look pretty.

I'll let you know how it works.


10/4/12 - after hitting every store that I thought might have such material I fell back to my trusty friend the interweb. Purchased (5)12" by .125" (1/8 inch) plexi rod and what I ended up with worked beautifully.

10/9/12 - after making a few minor adjustments in length and angle of the input end I decided to paint it and affix it to the detector body. I started with testor's spray chrome silver and then a light coat of matte back. Well ... this was not a good idea. Either I've underestimated the light gathering that is going on along the length of the plexi rod OR the paint changed the reflective properties of the inside surface of the plexi rod. It now only passes about 5% of the light going into it making it totally useless. I quickly made up a duplicate one and installed it with a few small dabs of silicone adhesive. (can be removed without trace)

How well does you duplicate version work? Can you post a picture of your "mod"? Thanks.

The 2nd prototype worked perfectly. I'd already worked out the material, dimensions, and build angles. It was just a matter of reproducing the bends as good or better then the first time around. I've been using this mod now for since the above date and love it. I leave the brightness set to auto.

TBH I was worried that it might transmit light too well and leave the display bright past dusk. Not a problem. I think one could even get away with not polishing the ends of the plexi rod.

(standard disclaimer applies. You screw it up, YOU, screwed it up!)

Pic1 - three screws on the bottom of the case.
Pic2 - Lift the bottom of the case off and the smoked end piece.
Pic3 - Lift the gutz out of the case and set aside (safe)
Pic4 - On the right what both sides looked like. Left is what I drilled out.
Pic5 - Where the surface mount light sensor is buried.

prt2: .... only 5 pics per post ....

Pic6 - the plexi-rod operational prototype 1. Painting it had unexpected results.
Pic7 - mounted to top of shell. Note the slight curve along its length.
Pic8 - front display cover removed. ~1/8" from plexi to sensor. Btw, the blue light is from my computer monitor 30" away entering the plexi rod.
Pic9 - what it looks like all buttoned up.
Pic10 - what it looks like mounted in the car. The input is about 1/2" from the glass.

The input nub is short enough that you can still put the detector in your shirt pocket w/o any hangups.

You're gunna ask so here is the answer. I used a small tab of 3M trim adhesive placed in the center of the metal window bracket minus the suction cups. I then applied a liberal amount of silicone adhesive every where else and used the trim adhesive to hold it to the window over night. Enough time for the silicon to set. If I wanted to remove it I could. But its NOT coming off by itself. You could use the black silicone adhesive and it might look better(?) but I used black gaffer's tape cut to the shape of the bracket to dress it up.

Hmm, ok that looks cool I guess. Given the choice of just using a manual setting or voiding my warranty and doing what you did I think I'll take option one.

okay - 6 month check in.

No issues at all, works exactly as designed. I've removed the detector from the windshield several times when parking at public parking in the city (Chicago) and it hasn't caused any hang-ups while placing in "hidden storage". Doesn't show any signs of coming off. It just works!

100% successful mod ! (IMO)

Just ordered a 9500ix. Does blue color and sensor still have the same issues? I've always had a V1 mounted behind the rearview with a remote display and compass in rearview is red. Just wondering in case I should change to red before it ships.
