A flashlight might make the level on a dipstick easier to see. Might also work for a sight glass
For sure, I sometimes use the one on my phone. But it's a pita with dirty hands while holding a dipstick.

I wonder why they don't just dye the damn stuff at the factory, like ATF! It's so clear it's really hard to see.

I bought some on line, it doesn't take much. My hydraulic guy tells me ATF is just hydraulic oil with dye in it.

In that they're both types of hydraulic oil, sure. But you wouldn't want to run regular hydraulic oil in an automatic transmission. ATF has a compound viscosity designed to vary less with temperature than conventional hydraulic oil, friction modifiers, as well as some detergents.

Mines tax-free even before the dye ... Ag exemption!
You are lucky in MO., In TN. all oil is taxable no matter if it is for tractor or not. They say you could use it in vehicles or mowers. I am Ag exempt also but doesn't help with the purchasing any oil

Instead of spending money on dye, maybe simply put it towards new glasses? 🤷‍♂️
