weird bulge on tach

anyone else experience this,I noticed it a while ago then convinced myself that it was always there and I just never noticed it.Then the other day I noticed it was partially deflated, and the reinflated as the truck was driven/warmed up, I will pull the dash and find out...I suspect a hot bulb or somthing??

I've got one on the temp gauge. I just assumed it was from the sun hitting it for years. But if yours inflates/deflates then yes, I suspect the bulb is to close

my temp gauge section has a few of them, none anywhere else

super cold temps deflate them

it is not caused by a bulb, it is a crappy layup +12 years

the temp gauge area

I have one that's a bit smaller, but in the same place.

User "Brilliant" on T4R had a HUGE one and ended up replacing the gauge face.
