Anyone ever change a bulb in a 52mm Omori boost gauge? I picked up one used and it has two bulbs burnt out of it. I wasn't told this so I didn't notice till I already had the gauge install and it turned night time.
I didn't get too good of a look at it but if I remember right it looked like the housing was solid. I don't remember seeing any way to take it apart.
If anyone has done it or knows how to could you please explain it to me before I go ripping into the gauge.
