Electronic control for Turn Signals

Higuys,

For convenience during highway driving as well as saving wear-and-tear, I thought it would be nice  to  incorporate a latching relay to operate the turn signals.  I just don't remember the type and current rating you'd need;  I think a simple 10A SPDT would work (for led bulbs)?  Then all you'd need is a stalk with a center-off SPDT  toggle switch (or a couple pushbuttons) to operate it?  A friend has it on an old truck, and I liked driving with it.

The only weird thing about the latching relays is that they seem to be all  PCB  mount  design.
