For this application you should be using a bench power supply with current limiting, not a "serial bulb" (I assume you mean a fuse, which is designed to break at a low current, however these are most typically rated for several amps, not typically in the mA range). You can set the voltage and a current limit. If the current goes beyond the limit, then the power supply will drop the voltage to keep the current below the limit or latch off. You can get a fairly cheap one for about $50-60 off of eBay, which won't be the best but is sufficient for hobby use

I dont like battle royales
Most of the time is spent just trying to get equipment or running from point A to point B, and by the time you've spent 15-20 minutes just running, one encounter means you lose
I play CS:GO. I like it because its more constant decision making, and the shorter rounds means less time investment into a single round. But it has gotten so bad with cheaters. I have played CS for over 15 years and yet I constantly run into brand new accounts or accounts that were clearly boosted (500+ commends in each category), bought, and used by cheaters who said that "it was cheaper than rust..." The matchmaking is so atrocious, I have people at the bottom of the ranks on my team and top of the ranks on theirs; the averages arent even close. I'm not playing CS:GO anymore and if CS2 doesnt fix the cheating problem, I'm not going back.
Ah. It's not going to be possible to size it because the bulb is then acting as a resistor essentially. Unless you know what the equivalent resistance of the circuit you're testing is, and it draws a fixed current, you aren't going to be able to cap the current; Adding a resistor (or bulb) is just going to drop the input voltage and you will probably end up having other issues
