Miniature LED lamps with bipolar function 

For miniature lamp sockets such as Bi-Pin, wedge-base or slide base lamps (telephone slide base, psb) the polarity of the lamp socket is usually not recognizable with DC supply.
If the lamp does not work on the first attempt, it has to be removed, turned over and put back in place.
This can be avoided by using appropriate lamps with bipolar function.

Signal-Construct offers both 2-way rectification lamps and dual-chip technology in the field of miniature lamp replacement.
As a result, these lamps are fully AC / DC compatible.

All standard LED colors are available, including warm white, with the following sockets:
