D.I.Y LED from direct-wire
Is it possible to run a single LED from the accessory socket on the direct-wire power adapter so I can have a discrete visual alert in my helmet & if so can anyone tell me how please?

Yes .Originally Posted by darkoh
Assuming this is 12 volts , you need to place a resistance 300 ohms on
one of the wire , does not matter the negative or the positive.

A single LED... not easily. The accessory port carries a serial data stream that would have to be decoded. Alternatively, you could tap the audio stream and drive an LED through a transistor, then the LED would light whenever the V1 beeps. That will tell you when there's an alert but no way to distinguish bands, etc.
Some guy on here posted a project where he decoded the various audio tones using a microcontroller and displayed them as different colors on a single LED, so that with practice you could "see" the alerts. I haven't seen him on in a while though.

If you want visual notification of alerts in your helmet, wouldn't it be easier to just purchase the Viz Alert or H.A.R.D kit?
