So if I wanna get LED bulbs for my cluster and climate controls, I'll need 194?
Edit - after some more reading, they may be 74's. That's the problem with information on the internet... Some sites are wrong.

I'm fairly certain when I got amber bulbs for my climate control (from Honda, Si model), they were the small 74's. I don't know where I got 194 from. I'll have to do more digging and change this.

I thought the little bitty ones were 74's.
They are. I know the climate control knobs are 74's. I replaced mine with factory Si amber ones and they're tiny. I can't speak for the cluster though.

Bulb incompatible apparently

I tried installing a 31mm DE3022 LED bulb today and it seemed to be a bigger than my stock incandescent bulb, and it seemed to bend my prongs in my dome light. Is that supposed to happen?

Here's a comparison photo just to be clear:

Top is Stock bulb
Bottom is new DE3022/DE3175 bulb



See the difference? It doesn't fit, and I don't know what to do.... Help please?
Oh yeah, and I have a 2000 Civic LX so a 6th Gen Civic.
