Hi Guys
Looking at the little circuit board that holds the hazard switch bulb and diff lock bulb. They look to be different. I was told by Olathe that they’re both 84999-70007, but I don’t think so. Is that the hazard bulb number or the diff lock bulb number? And does anyone know the other bulb number if there is one?
Many thanks!

From what I’ve read, it is the same bulb. Im about to replace the whole climate control bulb and switches situation with bulbs from Cruiser Design. I just replaced the vent bulbs and seat heater bulbs(they are different). Since I haven’t cracked open the dash yet, see if the diff light bulb looks like the one in this photo im about to attach.

Oooo , flip that board over and take another pic. Just found another thread on this by Matt Phelps in 2019 but it has a different type of switch setup. That thread has multiple bulb numbers. Im not savy enough to link it here.
 
Relaying info from another forum. The black bulb and the blue bulb are slightly different wattage. Im replacing the blue one with a black base- green bulb. I'll let you know how it turns out.
 
They are different wattage from the factory but you can put all the same bulb in if you'd like. I replaced just the bulb itself, not the base, with incandescent bulbs of a slightly-higher wattage. The diff lock and hazard backlights are brighter now, which is fine with me. I also left all of the colored covers off. Replacing just the bulb is easy and cheaper.

Do you happen to have the p/n for the seat heater switch bulb? I have one burned out and plan to replace this weekend. Thanks!
 
The seat heater switch will pry out easily, however when you try to take the cover off, be careful. I broke one of the side ears off and had to reglue it . I would warm up the switch to make the old plastic more pliable. Its an easy fix.
