Hi,

Is it possible to connect flashing led lights to the power instead of a battery. I've got them with 3AA batteries however I don't want to change them every now and then so I was thinking of connecting them to the power instead.

Is it possible? Or there is risk of overcharge coming from home power (internal resistance) instead?

Thanks

You’ll have to start again and explain what the lights do please!

Sorry. These flashing lights will be installed in a dummy alarm box.

Thanks

Just get the right LED setup and it will last 4/5 years.

With batteries running you mean? I don't think they might last that long.

Any recommendation of the right LED?

Thanks

Mains battery eliminator
Not sure how reputable or safe these actually are;
But you may be able to source a brand which carries a BS number or stamp which gives additional peace of mind.

I first saw the AA model at Christmas in my local B&Q
