    2000 Kenworth W900L flat dash i've changed all the gauge lights which were 194's and 1893's but the speedometer seems to have a different light source one that I'm having trouble finding, is it even possible to change the speedometer lighting? I swear I've seen it done in other trucks of the same year.

    There should be 2 lamps in the back of the Speedo head in those two holes. They are a ways in there. Far enough in that I use the pliers on a small Leatherman to grab the lamp holder. They’re the bayonet type push in, 1/4 turn to lock lamp holder. I’ve never seen anything else in a KW speedo unless the one you have is some sort of replacement with LEDs in it they should be there.

    That's the problem there's nothing but circuit board in those holes, the tach is exactly what you described but my speedo seems to be different

    Well, there’s a new one. My tractor is an ‘05 W900L. Both the original speedo head, and the replacement I put in a few years ago have the 2 holders in them.

    This wouldn’t happen to be one with the digital odometer would it?

    That’s what I was thinking. Your speedometer has been changed and likely lit by led soldered to the circuit board. There’s bound to be a gauge/instrument repair shop that can replace those for you.
