Default Where can I get this part?

The LED Bulb is burnt out on the Passenger Airbag Display. I took the old LED out and replaced it with a LED bulb I bought at Radioshack. The light lit up once and not will not light up. I dont know if it was the wrong resistance. I cannot find a piece to replace this part without ordering the whole radio bezel. Anyone know where I can get the whole assembly or even what LED I need to replace it with correct resistance? Thanks again.

Part number on the piece is 127791, that did not get me anywhere.

Hi.

You connected a ~3V LED to a 12 volt source. It's toast.

Buy either a 12volt rated LED, or another standard LED and a couple 1K ohm 1/4 watt resistors.

The 12v Led will drop right in - no extra parts needed. For the standard Led ....

... Try just one 1K resistor in series with the LED. If it's too bright, add the second resistor in series. If it's too dim, add the second resistor in parallel with the first.

I suggest this method because the mcd rating ( brightness) of the Led you buy is an unknown.

Ensure you observe correct polarity for the Led.



good luck

Great news! I went to radioshack and bought a 12VDC LED. Soldered it in. Drilled a hole in the clear plastic piece and it looks good. Total cost for the project was under $10 and now the airbags works again and no more light. Working on a project truck, now only a few more things to take car of. Thanks MGD!

Just for future reference the bulb they use for the passenger air bag light isn't a LED it's just a regular bulb which is why you fried the LED when you put it in the first time. Everything on these trucks is a LED for the most part except that passenger airbag light, pedal adjustment switch, the back lighting for the gauge cluster, and the center shift if you have one.
