Highliner Bulb Size

[Scottgenex]

Alright. I've searched and read. Searched some more. Checked all the websites selling the thing and can't find a real answer. I have a simple, easy one:

What size of bulb does the highliner speaker kit use?

I've tried 168 and 194 and no dice. It looks like that style of bulb socket but I can't get either to fit, so it's gotta be wrong. Don't necessarily want to keep buying packs of bulbs til I find one.

Thanks for the help.

I've gotta ask...
What's the "highliner speaker kit"?

It's a headliner that has speakers built into it that are directional towards your ears. They're OK. Not the best sound in the world. But it's a cool trinket to have I suppose. As shown in the link. No affiliation. Just an example.

What keeps those bulbs from fitting? Too wide? Too short? A little more info would go a long way.
