Stealth mirror display hard to see.

[ONRAILS]

This is my firs post and I have searched for a while with no results.

I installed a V1 remote display in my rearview (2 way) mirror everything looks awesome but the display is dim. I was thinking about putting a small light in the mirror that runs from the V1 power supply. What kind of led or light should I get and how would I wire it?
I am open to other ideas.

Thanks in advance

Make sure the light sensor on the remote display isn't blocked. The sensor controls the brightness of the LEDs, causing them to dim at night.

I just noticed that the sensor is behind the mirror and is blocked. The book says that we have no manual control over this.
Any Ideas?

If it were me I would probably find a way to carefully bore a hole in the mirror for the light sensor. That would take a whole lot of care and the risk of fracturing the glass, though. Either that or I would back-engineer the light sensor and replace it with a resistor to keep it at full brightness.

Is the led out of the question? The reason I ask is that it will not only take care of the dim display by tricking the sensor but with the light behind the mirror it should also let me see the display through the mirror better.

No, that's not out of the question at all. It might get annoying if the LED you choose is too bright but on the other hand it might work very well. The only tricky part will be getting power since they don't like anything over 1.5V. (I think 1.2V is usually nominal.)

Not tricky at all. Just connect a 600 ohm - 1K resistor in series with the LED (experiment to get the desired brightness).

Another idea is to try scratching or sanding the mirror coating off the glass directly behind the sensor. It might be tricky to get it looking just right but it would work, and allow the sensor to work (you want the display dim at night since cars/LEOS behind you can see it).

I will keep working on this and hopefully something will work out.
If anyone has any ideas on a led let me know.

I think I will take it to a shop and have them put a resistor in place of the sensor and if that does not work I will start with the led search.



BTW:Thanks for helping a noob.
