Beeper for turn signals?

[Ripped]

I have LED turn signal lights. No flasher to click, all electronics.

When doing a freeway lane change, sometimes I forget to cancel the signal, and it does not self-cancel.

I'd like to hook up a not-too-noisy tone/chime/beeper to the circuit so I don't drive along the freeway like a dummy, with my turn signal on, all the time
The old dash lights are small and dim, on a sunny day, not very noticable.

Any ideas?
