I have something in the works hopefully in the next month or so they will be available (then I will tell where)
I did this on my old Lumina and changed all the bulbs to green in the dash/hvac... this site here: www.autolumination.com Tail Light Brake Light Turn Signal LED Bulbs sells the correct wedge bulbs to just swap out, and the 194bulbs, and PC-194 bases to stick 'em in (for the dash) so you don't hafta solder anything... VERY simple to do... if I had pictures still I'd post up, but it's real easy, with nice results.
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
I doubt that will work. Unless the GP is very different from the Impala in that respect. All of the bulbs in the dash and switches are soldered in. There are no wedge bulbs or any really end-user serviceable bulbs at all. That's why this is a popular mod because if the factory bulbs burn out you have to solder anyway.
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.
stupid question. What kind of resistor is ior size i guess. and do you need it for all l.e.d bulbs
