LED bulb in pillar gauges?

[Silver200273L]

I took out one of my gauges and see what kind of bulb. The bulb is 168. But there is several bulb that will work for 168. Some LED bulb looks too tall to fit in my gauges. Some bulb will say T10 or T15. Not sure which LED I should get for my gauges.

Bump- Anybody?

194 interchanges. Probably a bit brighter

I knew that 194 and 168 work. But my concern is that some LED bulb will be too tall to fit in my gauges on the pillar. I guess I should measure how tall standard 168 bulb then find LED bulb that is same size as standard.

Oh. I have an LED 194 in my AutoMeter gauges.

How do you open the factory matched auto meter gauges?

You don't? Which model are you talking about?
I've got the Z Series and there is a bulb holder that twists out the back.

Idk what to tell you then. I haven't pulled them apart or even seen behind one before. Mine just has that bulb holder on the back.

BigD214,
The ford factory matched gauges from Auto Meter are LED lit. The part numbers should start with 84 (ie: 8457 for trans temp). You cannot open them up and change them. The LEDs are burried right behind the dial. It's not usually a problem though, becasue LEDs last a very long time (like 50 years or so).
