I have a hearing problem, it really is a PITA. I can not hear if there is too much background noise, I don't go to the pub anymore as I simply can't communicate. Like I said a PITA.

Driving the car creates another problem, I leave the indicators on as I can't hear the noise of the flasher. so today I bought 2 diodes and a 12volt beeper.

A wire was run from the positive to each indicator back to each of the diodes on the stripe side, join the other side of the diodes together connect to the beepers positive then earth the negative. Wrapped a bit of foam around it to stop it rattling and put it in the cavity beside the accelerator pedal.

The diodes stop the right side indicators turning on the left side and Visa - Versa or you could simply use two beepers.

Anyway it works a treat even with the music loud.
