What's the difference between these 2 test lights?

Decided to get a test light so I don't need to faff around with the multimeter every time I am fault tracing, and saw this "Car light tester" :

and then saw this "circuit tester" :

What's the difference!?

The 2nd one has easy to replace bulbs is all i can say TBH (i have both but never use them TBH).
If you can stretch to it a 12V probe is way better and all i use nowdays (see below) it does way more than test for live or earth it's also good for testing continuity, living up things (or indeed earthing things) and testing bulbs, fuses ect

One thing i will say is the metal one has a cap so when sticking your hand in the tool box there's less chance of drawing blood on the spike

Cheers So What, that probe looks just the job! As well as testing for continuity, will it test for voltage present? Using a multimeter at the moment but it's a bit slow witted (currently troubleshooting central locking so it's only a transient signal). I suppose the bulb one would be good to get too to check whether there is continuity but not enough to draw a decent current (as somebody else said).

That's great, just what I'm after - got a multimeter to check voltages, but a probe to check presence of voltage and continuity would be good. Can you detach the batt cables at all (I assume you only need them when you're powering up a component)?
