Has anyone figured out exactly which LED bulbs go in the instrument panel cluster yet?

These are NOT the 194's ! ! These are tiny little bulbs!

I read one thread that suggested it might be B8.4D from SuperBrightLEDs.com, (...I would like to know exactly which ones before I order them)

 

Are the bulbs you're wanting to replace the backlighting for the cluster (IE, the illumination with the rest of the dash, headlights on) OR is it the idiot light bulbs you're wanting to replace?

Backlighting and general illumination is usually done with 194s, and indication bulbs are usually #74 bulbs. #74 look like a baby brother to the 194s; as both are the 'mini wedge' design with the 'globe' of the bulb usually being a half-pill shape.

As far as clusters go, the 194s use large (usually black) twist-locker sockets. Indicator bulbs (CEL, airbag, seatbelt, door ajar) usually use tan, smaller, twist locker sockets.


Any pics you can post?

 

04+ clusters do not use 194s at all. They use a standard bulb I believe it's a 2721 or led 74.

 

On the 2005, the bulbs are a LOT smaller than the 194's. The plastic twist in socket says Toshiba V-2 on the bottom of it, and the bulbs are only 3/16" diameter while a 194 bulb is 3/8" diameter.

Hey Wolf! Whose number is 2721, Sylvania? Toshiba? Where can I buy them?

Whose number is the LED 74?

Do these include the plastic socket?

 

@Vista: This is news to me. Never would have guessed that.

@Michigan: Normally the bulb doesn't include the sockets, although some do. #74 is a generic cross reference number for that bulb.

I don't know what manufacturer uses 2721, though.

Here's an LED #74, that you may like. https://www.superbrightleds.com/more...rofit-car/228/

 

It should be a generic number like 194. But I have used the slyvania 2721 with no problems. The bulbs will be loose. You will reuse your holder

 

I have a 2006 fx4. Online showed instrument cluster lamps as 194 with T10 led replacement. I received the T10 with new bases and they are too big. Anyone had this problem and which part number they ordered to get the smaller Led`s
with base sockets?

 

I am trying to pass inspection and my check engine light is not coming on when I start my ranger. Because of this I failed the inspection and need to get that working in 60 days. I have removed the panel from the dash and it appears that the light is built into the circuit board and isn't an actual light bulb. Has anyone had this problem or have any idea how to repair it?
