Saw this today:
I get a catalog from All Electronics, which is surplus odd n ends...this little baby is a 12v strobe flasher that pulses 80x/min. All it needs is an enclosure and a 12v power source.
Would be great to have on the rig with an emergency switch so if you had to call 911 or similar they could find your rig in a hurry.
Click in picture for link to the catalog....I'm noodling what I could build with this....
Here's another interesting item from the same catalog:
12vDC motion sensor switch. Burglar alarm, lighting? Maybe for the bathroom light so it turns on/off by itself and doesn't get left on? Click pic for link.
