Two way testlamp
With this testlamp you can test for pos & neg. It can be fitted inside a medical syringe, using a piece of brazing rod as probe. By connecting the clips to the battery, the two led`s lights up dim, and if a positive is connected to the probe, the positive led will glow brighter and visa versa.

Re: Two way testlamp
Hi Piet,
Nice one! But are you sure the LED's are marked correctly? If the probe is connected to another positive, the LED marked "negative" will light up?
Cheers,
Chris
