It is RISKY BUSINESS to test 12 volt, 30 ma, LED lights, with an 800 amp
,12 volt battery (also very inconvenient). A short, to an engine battery
will cause big smoke, blisters, and much consternation.
It is possible to do the same testing with one fresh, or a few "dead " 9
volt batteries.

Often 12 volt LED lights are not tested by the Manuf. or when you buy them.
Using this tester, you can test them
with a battery from your pocket, and just before you install them, to make
sure all is working
There are a lot things that need to be tested , and you can do them all with
this little battery
good luck
