I bought one of the LED bar indicators which plugs into the earphone jack
on the Passport and never used it. I got a MINI Cooper istead of the Honda ST1300, a fair trade due to my wifes objections.
I'll get the paperwork out and sell it to you with all the mounting gear
and directions if your interested.
I it has 5 superbright red LEDs in a waterproof block of plastic
and just plungs into your detector eraphone jack.
I played abut $35 but would sell it for $25.
Let me know.
