I also had this idea of integrating a blinking security system light with the overdrive indicator light. I thought this would be simple. Once again Howard to the rescue with the circuitry diagram and suggested components. The turn signal wiring and components were also a bit of a mess, so I physically integrated them into the little plastic Storables box with a removeable lid that I got for the security light. The box is affixed to the face of the removeable radio faceplate with very strong 3M Velcro-like strips used for holding heavy items on a wall. As much driving as do, if I need to leave the car in a parking lot of a motel overnight, for example, I can turn on the blinking security light, whose flasher makes an audible clicking sound. It will only come on if the ignition is off and its switch is on. The GE#55 filament bulb was replaced with an equivalent (sort of) LED, which can’t wear the battery down blinking away all night. When the ignition is on, the bulb is reserved for its overdrive function. Howard is brilliant. Parts needed were
Newark SKU 67F3897, TE Connectivity K127E487 Relay Socket
Newark SKU 06R3606, TE Connectivity K10P-11D15-6 Relay Dpot quick connect

The Container Store Roll of black 8” cable ties
The Container Store Medium Storage Latch Box 10078035

See it in action. (http://www.mktx.com/packard/SecurityLightIntegration.MOV )
The LEDs (SOS-1MB-W-28, 6V to 28V BA9S white 1-chip Dome) I bought from SOS of Dallas are supposed to replace GE 55 filament bulbs. The bases have a slightly smaller diameter and will not stay straight in the socket and if bumped ever so slightly, pop out. I used one for the overdrive indicator light which doubles as a security light I can leave on all night without battery drain.
