Hi,

I put my tool box down on my standard Red alarm LED.

Just wondering if I can replace it with a blue LED. I need to know what voltage alarm LED's are supplied with by the alarm brain normally?

I can't imagine it's a full 12 volts...anyone have any ideas?

Thanks,

Depends on the alarm, alot of the alarms are 2V. Post the brand.

Always check info with a digital multimeter.

I promise to be good.

I've been sick lately, sorry I won't be on much.

It's a Selca alarm made by the people who make Toad alarms here in the UK.

I've bought some Blue LED's with the following spec, will these do: ?

REVERSE VOLTAGE:5.0 V

DC FORWARD VOLTAGE:3.3V TYPICAL/3.5V MAX

DC FORWARD CURRENT:20mA

Thanks, Mo
