Hello,
So, I recently "redid" my HVAC assembly using new 12v LEDs for the HVAC display. (long story). Anyway, as you may now, the factory backlight is 6v, I did a reverse polarization to my screen and am using (trying) 2 LEDs rated at 12v (I tapped the radio power). 12v+ coming from the radio power and the negative from the assembly's negative.
Following are the "sockets" for the factory bulbs that illuminate the HVAC display. Note the + and - . (positive side not used, but negative is for dimming)
So then, because my assembly was butchered (too much solder was placed onto the contacts, so a factory bulb or LED can no longer be "inserted"), an LED or bulb has to "sit" on top of it. For the negative part to make contact, I taped it hoping it would secure it. I was wrong.
I tried removing the excess solder, but was unsuccessful.
I used tape to secure bulbs in place.
Here is a picture when I hooked up the LED to the 12v wire. Obviously, no light.
Here is a picture when I put pressure on the bulbs. Doing this obviously makes the base make contact with the negative thus turning the LED on.
My question to ya'll is:
1) How/what should I use to adhere the bulbs? Soldering came to mind, but I'd rather not do that.
If you guys have any suggestions, let me know!
