Blue led dash conversion

Have you decided on color scheme? Aside from the mod party tomorrow, I don't have any appointments now. PM me when you're ready to nail down the deets.

 

Yep, that's the one.

 

Here are some snapshots of @bonchang's retrofit.

 

Very Nice !!

 

This is @sd1810's retrofit.

 

Pictures don't give justice to the LEDs. They can be appreciated more if seen live in action.

 

I got the Bi-color LEDs ready for the next mod party. Mostly blue-red and some white-blue.

 

I didn't get any good pictures of @Gaspeed's setup.

Awesome! That will be breaking some new ground.

 

Excellent @bonchang, please save me a blue-red combo.

 

The ever gracious host is one of the few on top of the list

 

Some fresh shots from my retrofit.

Plz save me a red/blue combo if u can


iPhone ?

 

You know you're on top of the list too

 

I have made some revisions & updates to the "Shopping List" post.

The main difference is that I'm suggesting Oznium 0805 type LEDs for Toyota head units.

 

Looks awesome! Totally reminds me of my old VW. Can't wait till you figure out the main dashboard lighting.

 

The dash cluster.....that's in the plan

My bulbs came in!

 

Another excellent job by SiFu Dylan!

 

Forgot about the heater

 

So, you want your passenger side lock switch to illuminate the same as it does on the driver side?



Just because it doesn't illuminate now doesn't mean it can't. Let's take a look inside.



So, evidently this switch is designed to illuminate in some cars. Just not the Prius (or my wife's Yaris).
I did some digging and I was able to find a Lexus CT200h switch that is the same, but different.



You can see in the Lexus version of this switch there is a B15 zener diode, a 1.3K resistor, and an LED. The Toyota version has the same circuit board, but lacks the components.

Looking at the wiring harness inside the door handle, we also notice that the Toyota wiring harness lacks power for the illumination pin.
To resolve this problem I scavenged a wire from an extra connector and stuffed it in the empty slot on the lock switch connector. Then I spliced that into the illumination line (white with yellow bars) on the neighboring window switch connector.

The last obstacle to lock switch illumination nirvana is getting the new LED light to pass through the opaque switch cover. (The Lexus switch cover is made of translucent plastic.)



To deal with this, I drilled a tiny hole and added three lines of fiber optic to pass down to the inner realm where the LED lies. Cap that with a thick drop of slow drying super-glue and you're done!



Ideally you should use a single, more thick, fiber optic line -- maybe 1/8", or 3/32".
