Yeah, GM loves to tint the overlays to get the right color. They used yellowish bulbs behind a blue overlay to achieve the Impala/Monte factory colors.

If you took white LEDs/bulbs and stuck them behind the factory cluster it would glow blue. Even though I have a new overlay, I still have white LEDs behind it and it still glows blue. The red warning areas and red needles look GREAT that way.

Making you think twice before picking on Impalas

that is freakin sweet, thats what I want the whole dash and buttons on my car to look like. So I just need to replace all the factory leds with white ones and I'll get that same effect?

What would I have to do to change the needles to glow like white or some other color

According to archemedes your factory overlay is tinted reddish/orange so you need a new overlay that will allow for these colors.

Find new needles.

With respect, is that the same scenario for the gauge cluster and the hvac lights?

On the lumina (I assume it can't be TOO different for many cars) it called for 6 PC-194 quarter-turn bulbs (a 194 with a base that it sat into, which kinda screwed so to speak into the circuit board) and the HVAC bulbs were... 37's? Two to be exact... I never looked at the door switches or anything. Sorry if I caused some confusion. Autolumination.com DOES sell some really cheap pre-resisted LED's as well though.


In regards to the question about changing the needle colors... I would think you'd need replacement needles for that.

That's what I was referring to when I said "bulbs in the dash" meaning the gauge cluster and the HVAC.

The factory 00-05 Impala/Monte radio, gauges, and HVAC controls use thin wheat style incandescent bulbs soldered to the PCB.

Understood, thanks for explaining the difference to me.

stupid question. What kind of resistor is ior size i guess. and do you need it for all l.e.d bulbs

The resistor you use depends on what LED you use (see the Ohm's law formula I posted previously in this thread). Resistors are required for any LEDs that don't have a built in resistor.
