Well If you don't want the Ram system(and I'm not knocking the ram system) go to wal-mart or kay mart and buy one of those jogging flashing lights for about $2.00. Take all the lences off and other things you wont need and soder some wires where the led goes and get a high intensety led and attach to the wires (test polarity before sodering) and locate the beacon where you want it. I did this on my A-26-B invader and can leave the lights on all day and won't miss a beat or run down. But thats me. On my B-25 I have the ram beakin and nav lights.
