If you own a WINAMOO WITL103A circuit tester and the bulb’s gone out, don’t sweat it.
This little 5-pack of replacement LED bulbs is exactly what you need.

They work for 6 to 24 volts, so they’re good for most automotive electrical checks.


Each bulb is built to last longer than those old-school incandescent ones, so you won’t be swapping them out every other week.
And having five in the pack means you’ve got spares for when you inevitably lose one in the shop.

Simple, affordable, and gets the job done.
