You just can't go wrong using electronic flashers.
They can run anything in the way of bulbs, now or later and they don't quit flashing if a bulb goes out.
The downside with using electronic flashers is that they will flash no matter what. In other words you'll never know if you have a blown out bulb unless you look from time to time.
The one downside.
I check mine in store windows and places like that usually.
Normally I do a walk around light check anyway about every week or so.
